IntelliJ IDEA Tips & Tricks: Presentations

Presentation Mode

Since IntelliJ IDEA 13, you can switch to Presentation Mode by clicking View → Enter Presentation Mode . The IDE switches to full screen and everything is hidden except for the main editor window. The font size is increased so it is better readable from a distance.

The font size in Presentation Mode can be configured in Settings under:

Distraction Free Mode

Distraction Free mode is another view mode you can use. It is similar to Presentation Mode at first glance but has several important distinctions.

It hides everything except the Editor window and centers it. All the toolbars and panels are gone. Unlike Presentation Mode, it does not increase the font size, but it rather keeps it unchanged. Additionally, it does not enter full screen, so you can use it even in a small window. That may be useful when having code editor on half of the screen and something else (like a browser window or terminal) in the other half.

As the name suggests, it is intended as a convenient way to hide all the visual clutter, when you need to focus just on some particular piece of code. After the Presentation mode was introduced, many were using it not only for presenting but also as a Distraction Free mode, which was later released as a separate feature in IDEA 14.1.

While the Distraction Free Mode was not originally intended for presentation purposes, there are situations, where it can be more appropriate that original Presentation Mode. Because the size of the font is not changed, you can see a much bigger portion of the code at the same time. This gives you the much better context that seeing just a small snippet of code at once without the surrounding code. This may not be suitable for regular presentations with one big screen and listeners, who may be too far away to read the code. However, it is much better for scenarios where each listener has their own screen and can read even the smaller font. Such situations would be for example video conferences with screen sharing or webinars. For this purpose, you should consider Distraction Free mode as a viable alternative to the regular Presentation Mode.

Note that Presentation and Distraction Free Mode are not mutually exclusive and can be active at the same time.

To enter this mode go to

UPDATE: Zen Mode (2020.1)

Idea 2020.1 introduced Zen Mode . It is just a convenience feature, which combines Distraction Free Mode and Fullscreen as these are often used together. Previously it was quite inconvenient to toggle them both. To enter Zen Mode go to:

Presentation Assistant Plugin

After you achieve a basic level of proficiency with your IDE and already know which features it offers, your next goal is to increase your productivity. That is, you want to use the tool you are already familiar with more effectively. A major part of that is using the keyboard as much as you can instead of the mouse. Using keyboard shortcuts where possible. Great way to learn IntelliJ IDEA shortcuts is to use Key Promoter plugin . Once you use mainly keyboard, you are much more productive. The problem is, using a lot of keyboard shortcuts is not exactly presentation friendly. Your audience can get quickly confused and lose track of the core topic you are presenting about while trying to figure out what the hell just happened.

Fortunately, there is a nice tool, which helps you exactly with this issue. It is Presentation Assistant Plugin ( GitHub ). Every time you trigger an action (no matter whether with the keyboard or mouse), it shows the action name and a keyboard shortcut associated with the action. What's more, it shows the shortcut both for Mac and Linux/Windows.

This is obviously very handy when having a presentation as the audience exactly knows which actions are you triggering using the keyboard and what shortcut is associated with them. Usually, this way they can learn not only about your main topic but also a handful of new and useful IDE features/keyboard shortcuts. And your talk is not constantly being interrupted by questions about actions and shortcuts you just used.

This is not only useful while presenting, but also when pair programming. This way your partner can keep track of your actions and maybe even learn a thing or two. Last but not least, using this plugin can help you to learn new shortcuts because it shows the shortcut info even for actions triggered by the mouse. That means that eventually, you will learn shortcuts for actions that you currently use only by mouse. However, you may consider using Key Promoter plugin for this scenario.

Keyboard shortcuts

Both the Presentation and Distraction free modes have no keyboard shortcuts associated by default. By default, they are only accessible from View → Enter Presentation Mode and View → Enter Distraction Mode . You can, however, assign custom shortcuts to these actions as usual.

Alternatively, you can use Quick Switch Theme action ( Ctrl + ` or ⌃ + ` on Mac) and Then press 4 (View Mode). From the subsequent popup menu, you can pick either Presentation or Distraction Free mode. This shortcut is also useful for quickly switching keyboard layouts, code styles, look and feel or color schemes.

Mouse wheel zoom

Sometimes your editor font size is just right, but you want to temporarily zoom in for specific detail or zoom out to see the big picture. IDEA offers similar functionality to browser zoom change. You can adjust font size in the Editor by Ctrl + Mouse Wheel.

This feature is not, however, enabled by default. You need to turn it on in Settings:

Then check the following checkbox to enable the zoom functionality:

The regular Presentation mode offers a good tool for presentations with one big screen. For webinars and other situations, where each viewer has their own screen, it may be better to use Distraction Free Mode, where the font size is not changed, therefore the viewers can see more code at once, so it offers more context. This way you are always ready for these two possibilities without the need to manually alter font size in the settings before each presentation. In either case, it is really handy to use Presentation Assistant plugin, which lets your viewers clearly see all the actions and keyboard shortcuts performed.

In this article, we will take a look at ways to level up your presentation skills with IntelliJ IDEA.

Presentation Assistant plugin

Our first tip is to use the Presentation Assistant plugin. The Presentation Assistant plugin will show which shortcuts are being used.

To install the plugin, open Preferences using ⌘, (on Mac) or Ctrl+Alt+S (on Windows/Linux). Go to Plugins and search for "Presentation assistant" on the Marketplace tab. Click Install and when it's done, click OK to apply the changes and close the dialog or click Apply to keep the dialog open.

To configure the Presentation Assistant plugin, go back to Preferences and go to Appearance & Behavior > Presentation Assistant .

Here we can configure font size, duration, alignment, and which keymaps to show. We are using macOS, with Windows as the alternative keymap. We have also configured the Presentation Assistant plugin to show the shortcuts at the top of the screen.

Presentation Mode

When presenting, you can use Presentation Mode . The IDE switches to full screen and everything is hidden except for the main editor window. The font size is increased, so it is easier to read from a distance.

You can switch to Presentation Mode by clicking View > Appearance > Enter Presentation Mode .

Exit Presentation Mode by clicking View > Appearance > Exit Presentation Mode .

If needed, the font size in Presentation Mode can be configured in Preferences > Appearance & Behavior > Appearance . Scroll down to Presentation Mode , and font size and set the font size you want. Click OK to apply the changes and close the dialog or click Apply to keep the dialog open. Click Cancel to discard the changes and close the dialog.

We can also open Presentation Mode using short-cuts. Open the Quick Switch Scheme using ⌃ BackTick (on Mac) or Ctrl+BackTick (on Windows/Linux). Use the arrows to select View Mode and then select Enter Presentation Mode .

We can use Quick Switch Scheme again to Exit Presentation Mode .

To enable mouse zoom, you need to turn it on explicitly. Go to Preferences > Editor > General and select Change font size with Command+Mouse Wheel (on Mac) or Change font size with Control+Mouse (on Windows/Linux). Click OK to apply the changes and close the dialog or click Apply to keep the dialog open.

Now we can use Command+Mouse Wheel (on Mac) or Control+Mouse Wheel (on Windows/Linux) to zoom in or out. While we are using mouse zoom, a popup appears containing the current font size on the left and a link to reset to the original font size on the right. Click the link to reset the font size.

To configure font and font size, go to Preferences > Editor > Font . We can select the font we want to use, and set the font size.

When presenting in person, make sure the font can be read from a distance. If possible, check out the room where you'll be speaking, do your setup before your talk, and walk to the back of the room to check if the code is readable.

By default, IntelliJ IDEA uses the Darcula theme. To change it, go to Preferences > Appearance & Behavior > Appearance .

Select the UI theme from the Theme list:

• IntelliJ Light is a traditional light theme for IntelliJ-based IDEs
• macOS Light or Windows 10 Light is an OS-specific light theme available as a bundled plugin
• Darcula is the default dark theme that we're using here
• High contrast is a theme designed for users with color vision deficiency

Which theme to use depends on your personal preference. When presenting in front of an audience, you may want to take into account how light or dark the room is. If possible, try different themes and walk to the back of the room to see which one works best before your presentation. When sharing your screen during an online meeting, you may also want to check with teammates which theme works best.

Tool windows

We recommend closing all unused windows so we can focus on the code we're looking at. Use Command + Shift + F12 (on Mac) or Control+Shift+F12 (on Windows/Linux) to hide all tool windows.

We can always reopen them using shortcuts. Here are the shortcuts to some of the most used windows:

• To open or close the Project Tool Window use ⌘1 (on Mac) or Alt+1 (on Windows/Linux)
• To open or close the Commit Tool Window use ⌘0 (on Mac) or Alt+0 (on Windows/Linux)
• To open or close the Terminal Tool Window use Alt+F12
• To open or close the Git Tool Window use ⌘9 ( on Mac) or Alt+4 (on Windows/Linux)
• To open or close the Run Tool Window use ⌘4 ( on Mac) or Alt+4 (on Windows/Linux)
• To open or close the Debug Tool Window use ⌘5 ( on Mac) or Alt+5 (on Windows/Linux)

You can also use keyboard shortcuts to stretch the active window. Go to the relevant window, and use ⌃ ⌥ ← or ⌃ ⌥ → (on Mac) or Control+Alt+Shift+Left or Control+Alt+Shift+Right (on Windows/Linux) to stretch the window left or right. This also works with the tool windows at the bottom, using the up or down arrows to stretch the window up or down.

Find action

If you want to do something, but don't remember the shortcut or menu option, use Find Action . Press ⇧⌘A (on Mac) or Control+Shift+A (on Windows/Linux) to open the Find Action dialog. Search for the action you want, and select the relevant action.

For example, let's use Find Action to apply soft-wrap.

When using a file that has long lines, we can prevent horizontal scrolling by using soft-wrap. Let's use Find Action to enable soft-wrap. Press ⇧⌘A (on Mac) or Control+Shift+A (on Windows/Linux) to open the Find Action dialog, and search for "soft-wrap".

We get the option to turn on soft-wrap, which will be for this file only. You can click this option to turn soft-wrap on or off.

Alternatively, we can configure soft-wrap. Let's select " Soft wrap these files ", which will soft-wrap several types of text files. Click OK to apply the changes and close the Preferences dialog.

We recommend using shortcuts as much as possible when presenting. This is easier to do during a presentation than using a mouse or trackpad, especially if you get nervous and your hands might get slippery. There are several ways to learn shortcuts.

• Find Action lets you search for commands and settings across all menus and tools.
• Key Promoter X is a plugin that shows a popup notification with the corresponding keyboard shortcut whenever a command is executed using the mouse. It also suggests creating a shortcut for commands that are executed frequently.
• If you are using one of the predefined keymaps, you can print the default keymap reference card and keep it on your desk to consult it if necessary. This cheat sheet is also available under Help > Keyboard Shortcuts PDF .
• To print a non-default or customized keymap, use the Keymap exporter plugin .

Let's take a look at some shortcuts for navigation.

We can use several shortcuts to navigate around a project:

We can Find a class using ⌘ O (on Mac) or Ctrl+N (on Windows/Linux).

We can move the caret to a method and use ⌘ B (on Mac) or Ctrl+B (on Windows/Linux) to go to the declaration or usages.

We can also navigate backwards by using ⌘ [ (on Mac) or Ctrl+Alt+Left (on Windows/Linux), or navigate forward: ⌘ ] (on Mac) or Ctrl+Alt+Right (on Windows/Linux).

Use ⇧ ⌘ E (on Mac) or Ctrl+Shift+E (on Windows/Linux) to find Recent Locations .

Or find Last edited location with ⇧ ⌘ ⌫ (on Mac) or Ctrl+Shift+Backspace (on Windows/Linux).

Finally, we can find Recent Files using ⌘ E (on Mac) or Ctrl+E (on Windows/Linux).

Another way to navigate through code, is to use bookmarks. Press F3 (on Mac) or F11 (on Windows/Linux) to create an anonymous line bookmark.

To add a mnemonic line bookmark, press ⌥ F3 (on Mac) or Control+F11 (on Windows/Linux). In the popup that opens, select a number or a letter that you want to use as an identifier for this bookmark. Press ⏎ (on Mac) or Enter (on Windows/Linux) to save the bookmark. To bookmark files, packages, folders, and modules, right-click the item you want to bookmark in the Project Tool Window , and add an anonymous bookmark ( F3 (on Mac) or F11 (on Windows/Linux)), or a mnemonic bookmark ( ⌥ F3 (on Mac) or Control+F11 (on Windows/Linux)).

There are several ways to navigate between bookmarks. Press ⌘ F3 (on Mac) or Control+F11 (on Windows/Linux) to open a popup showing bookmarks and select the desired bookmark with the keyboard and press ⏎ , or select the corresponding digit or letter for a mnemonic bookmark.

To jump straight to a mnemonic bookmark, hold ^ (on Mac) or Control (on Windows/Linux) and press the mnemonic digit or letter on the keyboard.

As developers, we’re all familiar with debuggers. We use debugging tools on a daily basis – they’re an essential part of programming. But let’s be honest. Usually, we only use the breakpoint option. If we’re feeling frisky, we might use a conditional breakpoint.

But guess what, the IntelliJ IDEA debugger has many powerful and cutting-edge features that are useful for debugging more easily and efficiently.

IntelliJ IDEA has a presentation mode (View->Enter presentation mode), that makes the IDE full screen, increases font sizes and hides unneeded inspectors and other stuff that is normally in use when programming.

Manually inserting the setting

This is now possible by manually inserting the registry key in a file that your editor picks up.

Find the config directory for your IDE:

Go to ~/.config/JetBrains/ , then open the folder for your <product><version> .

Example: ~/.config/JetBrains/WebStorm2024.1

Go to %AppData%\JetBrains , then open the folder for your <product><version> .

Example: C:\Users\Webber\AppData\Roaming\JetBrains\WebStorm2024.1 .

Go to ~/Library/Application Support/JetBrains then open the folder for your <product><version> .

Example: ~/Library/Application Support/JetBrains/WebStorm2024.1

In that folder, create a file called idea.properties with the following contents:

Restart your IDE and go to presentation mode

How to switch to a editor tab in Presentation mode?

I have seen other posts here of folks who have problems with tabs and tools being closed upon returning from Presentation mode. I don't have that problem. Everything is in the same place after exiting Presentation mode.

However, what I *would* like to do is to switch to a different editor tab while in Presentation mode. The key to move to the next or previous tab (Alt-left, Alt-right) do nothing. I have to exit from Presentation mode, go to the next tab I need to present, and then re-enter Presentation mode.

Is this a bug? Is this expected behavior?

I am using PhpStorm, build #PS-171.4694.2 with Linux Mint 18.1.

A possible workaround would be using Switcher (Ctrl+E). However I think it's fair to say that this is a bug - the tabs switching keys should work in the Presentation mode as well. Please submit a bug:  https://youtrack.jetbrains.com/newIssue?project=IDEA

Thanks for your response. I have submitted the bug .

IntelliJ IDEA 之 呈现模式（Viewing Modes）

写在前面 IntelliJ Idea 为用户提供了多种呈现模式，在某些情况下，默认呈现方式有可能无法满足你的需求。例如上线之前会有一个代码评审的环节，Idea 默认展现出来的代码看上去会不舒服，因为 Idea 还会呈现除代码之外的内容：菜单栏、工具栏、导航栏等。

题外话 我是沂蒙山区的孩子，像音频里说的一样，现在乡下已经无法听到 “卖小鸡吆，卖小鸡吆” 的吆喝声了，连养鸡的农村人也越来越少了。

+ Idea 全屏模式

演示环境 ，介绍本次远程调试所依赖的软件环境。

+ IntelliJ IDEA :2018.2.4 (Ultimate Edition) 

+ Windows 10 家庭中文版

IntelliJ 用户界面介绍

Intellij Idea 主界面中包含几个重要的组件，例如菜单栏、状态栏、工具栏等，认识这些组件及其功能会帮助你更好的了解 Idea 的更多功能。

菜单栏和工具栏：菜单栏提供了项目级别的命令，例如创建新的项目、重构调试代码等。工具栏是菜单栏功能的子集，类似于菜单栏的快捷键，可以快速访问某些较为常用的功能。

导航栏：类似于面包屑，可以快速导航至文件路径中的任意文件。

状态栏：显示当前项目、IDE的状态和警告信息。

编辑器：阅读、创建和修改代码。

工具窗口：辅助窗口用来展示一些特殊的任务，例如文件检索，项目调试，版本控制等任务，这些任务较为复杂，需要较大的窗口来展示任务内容。

Idea  全屏模式（Full Screen）

在全屏模式下，你可以使用整个屏幕进行编码。因为全屏模式下会隐藏菜单栏和操作系统控件（例如状态栏）

Idea  演示模式（Presentation Mode）

演示模式下，Idea 会隐藏掉除编辑器之外的所有的组件，而且会放大代码字体，这样子整个屏幕上均是你的代码，看上去会舒服很多。

Idea  集中模式（Distraction-free Mode）

集中模式下，编辑中的代码会居中显示，这样子你会更容易将注意力集中在目标代码上，这也是跟其他模式区别最大的地方。

附件和注意，包括上述 Gif 图片中的配置信息和测试代码片段，若有任何未提及到的内容，请联系我。

在某个阳光灿烂的下午，也许你会想起全屏/演示/集中模式，因为这是你的生活，哈哈。

The Lightning-Smart IDE for PHP Programming

Full Screen for all platforms and Presentation Mode with PhpStorm 7

We’re continuously working on making the IDE distract developers less when they need focus. Next to better readability with improved syntax coloring , PhpStorm 7 comes with a Full Screen mode on all platforms which removes window borders and the top menu. And the new Presentation mode helps you show off your coding skills to an audience.

This functionality is available in IntelliJ IDEA , PyCharm , WebStorm , PhpStorm , RubyMine and AppCode .

Mac OS X users have been enjoying native Full Screen mode for quite a while. From now on it’s available for all other platforms supported by PhpStorm. It can be activated from the View | Enter Full Screen menu. To maximize the editor area, the Toolbar, Status Bar and Navigation bar can be hidden so we can focus just on our code. Here’s a blatantly big screenshot demonstrating we get a lot of editor on our screen if we want:

Always wanted to show family and friends your coding skills on the living room TV? Or are you presenting at conferences and user groups or doing classroom trainings? Having difficulties reading someone’s code when looking over their shoulder? The answer to making code work for an audience is PhpStorm 7’s Presentation Mode.

Presentation Mode moves all toolbars out of the way and increases the size of everything in the IDE, making it easier to show our code and coding process. That’s right: it’s presentation mode, not read-only mode. If you want to demonstrate live coding, try it from the View | Enter Presentation Mode menu:

Not only editor fonts are increased in size: everything gets bigger! Want to show the Rename refactoring? Everyone will be able to read what’s on screen:

多年总结IDEA 使用技巧 (建议收藏！)

很长一段时间没有更新了，前段时间转测试了，浪费了一些时间，终于可以写文章了，今天来写一下之前自己开发的一些习惯，因为自己本身自己是一个极简主义所以 开发喜欢这样:。

我们可以使用【Presentation Mode】，将IDEA弄到最大，可以让你只关注一个类里面的代码，进行毫无干扰的coding。

可以使用Alt+V快捷键，弹出View视图，然后选择Enter Presentation Mode。效果如下：

鼠标移上去就会这样显示时间, 是不是很酷,移开就是全屏

这样看代码，个人认为比较舒服

屏幕太多了，一直用鼠标也比较麻烦，这里我们可以直接 Ctrl+E 进行页面切换

有的时候，我们项目改变并不是很大，其实不用热部署，直接编译就好了，这样可以达到快速重启的目的

AutoCompletion

当我们要输出某一段内容的时候，很多人习惯想到 sout + Tab 这是我们IDEA 的输出快捷键 ，但是其实开源更简单 ，大家可以， 输出一段字符，在点 sout，这样就直接输出啦

这里就懒得做gif动图，直接截图的好

有时候我们想要定义一个成员变量，怎么办，通常都是直接把光标移入到 全局作用域的地方 ，输入我们要定义的变量名， 然后在 输出 ，有了下面的方式就好啦

很多时候，我们都需要做这些的操作，我们来看一下下，没用gif，可能图片有点多，适当看哈

快速的开发常见操作 ：补全、判空、循环、取反

循环 ,这里的循环，我换一种操作，定一个容器，集合、数组都行，我们来试试， 然后 .fori

很多时候，在俺们开发当中，经常会方法调用方法，有时候一段代码过于的冗余，所以需要进行抽取，脑补以下，代码超长的感受

有的时候，咱们在需要快速定义局部变量，这样子

还是一样，字符串，这回，咱们换个快捷键，输入 Ctrl+Alt+C 抽取静态变量

知道套路，咱们 就只说快捷键和效果，就省略，那些重复的图啦！

有的时候，我们使用的变量，往往要变成一个参数传进来，怎么做呢

这个也是最重要的核心，咱们再来讲讲 ，内容过多，抽取方法

还是字符串，输入 Ctrl+Alt+M ，就会自动抽取成方法

编辑 代码块 ，进行一个常用的操作

下面我们来看IDEA 中那些神奇的提示操作, 除了最基本的代码提示功能，IDEA 还提供更加智能的代码提示功能，该功能可以基于上下文环境，智能帮你过滤可以使用方法，推导出最适合的方法。该快捷键为 Ctrl+Shift+Space。

我们用下面两张图比对两者的区别。

此外，我们还可以用该快捷键完成下面的操作。

Postfix Code

这个模式可以在编写代码时减少向后插入符号跳转。我们可以在变量后面直接跟上 if、for 等表达式，IDEA 会直接转换成相应的语句。

Live Template

我们有时候会保存一些代码片段，然后在需要的时候直接粘贴。而 IDEA Live Template 就可以帮我们保存这个代码片段，且可以自定义关键字，需要的时候只需要输入关键字，就可以直接输出代码。而且 IDEA 也已经定义很多，我们可以直接上手使用。

输入 psvm，快速生成 main 方法。

开发的时候我们会去查看类的源码,有时我们只知道类的名字，却不知道具体包的位置，这个时候IDEA 强大的搜索功能可以帮我们迅速的找到。

这个功能不仅可以找类，也可以用于找文件等。

还有的时候我们可能只记得类中的某个关键字，那上面的方法就无效。但是没关系，IDEA 还可以帮你用关键字去搜索找到 我们只要输入 Ctrl+Alt+F 快捷键。

在相同内容后生成光标，一个一个选择

当我们打开的标签页多了的时候，默认的会隐藏在右侧，当我们需要的时候在右侧找到后再打开。IDEA是支持多行显示的，这样在大屏幕的显示器上也不用总去点击右侧的去找刚才打开过的文件了 File - Settings - Editor - General - Editor Tabs

IDEA 自带快捷地址

为什么这个点，要单独写一个标题来讲呢，因为，很多人没有注意到这个细节，IDEA，大家都知道我们安装了IDEA 是这个 样子的

打开之后，我们 再来看下

• 这么干净的快捷键列表，是不是很整齐，大家都疏忽了这么这么一份 IDEA的宝典

好了，文章就写了这里，洗洗睡吧，明天，还有上班

JetBrains Rider 2024.2 Help

Ide viewing modes.

JetBrains Rider lets you switch between several viewing modes for different usage styles and scenarios. For example, when you need to focus on the code or present to an audience.

JetBrains Rider expands the main window to occupy the entire screen. On macOS, all operating system controls are hidden, but you can access the main menu if you hover over the top of the screen.

The editor occupies the entire main window with the source code centered. All other elements of the UI are hidden (tool windows, toolbars, and editor tabs) to help you focus on the source code of the current file. You can still use shortcuts to open tool windows, navigate, and perform other actions.

JetBrains Rider expands the editor to occupy the entire screen and increases the font size to make it easier for your audience to see what you are doing. Other elements of the UI are hidden, but you can bring them up with corresponding shortcuts or using the main menu if you hover over the top of the screen.

JetBrains Rider combines the Full Screen and Distraction-free modes, so the main window expands leaving only the editor with the source code for you to focus on programming.

If you work on a smaller screen, you can enable the compact mode. In this mode, the IDE has the reduced heights for toolbars and tool window headers, scaled-down spacings and paddings, and smaller icons and buttons.

By default, the editor text in the Distraction-free and Zen viewing modes is centered vertically and the text column width corresponds to the Hard wrap at option on the Editor | Code Style page of settings  Ctrl+Alt+S . This means that if your code will be centered when formatted properly , but if there are long unwrapped lines, the text might go beyond the viewport while there is a large margin on the left. In such cases, you may want to decrease the left margin using the Left margin in distraction free mode option on the Advanced Settings page of settings  Ctrl+Alt+S .

Toggle viewing modes on and off

In the main menu, go to View | Appearance and select Enter <viewing mode> or Exit <viewing mode> .

Use the quick switcher:

In the main menu, go to View | Quick Switch Scheme (or press Ctrl+` ).

In the Switch popup, select View Mode and then select Enter <viewing mode> or Exit <viewing mode> .

Use Find Action : press Ctrl+Shift+A , and start typing the name of the viewing mode. Then select Enter <viewing mode> or Exit <viewing mode> from the list and press Enter .

Map actions that toggle viewing modes on and off to your preferred key combinations .

By default, only Toggle Full Screen mode is mapped to ⌘ ⌃ F in the Visual Studio keymap .
