If you use one of the predefined keyboard mappings in your operating system, you can print the default keyboard mapping reference card and leave it on the desktop for review as needed. The cheat sheet can also be found under help | help. Keyboard mapping reference.

Choose the correct keyboard mapping

To view the keyboard mapping configuration, open the Settings / preferences dialog box, Ctrl+Alt+S and select Keyboard Mapping.

Use predefined keyboard mappings

IntelliJ IDEA automatically recommends a predefined keyboard mapping based on your environment. Make sure it matches the operating system you are using, or select the operating system that matches the shortcut in another IDE or editor you are used to, such as Eclipse or NetBeans.

Adjust your keyboard mapping

You can modify a copy of any predefined keyboard map to assign your own shortcuts to commands you use frequently.

Import Custom Button Mapping

If you have a custom key mapping that you are used to, you can transfer it to the installation.

In addition to the default keyboard mapping set, you can add more plug-ins (such as keyboard mappings for GNOME and KDE): open the Settings / preferences dialog box Ctrl+Alt+S, select plug-ins, and search for keyboard mappings in Marketplace.

Learn shortcuts at work

IntelliJ IDEA offers several possibilities for learning shortcuts:

The find operation is the most important command, which allows you to search for commands and settings in all menus and tools.

Press Ctrl+Shift+An and start typing for a list of recommended actions. Then select the necessary actions and press Enter to perform them.

Key Promoter X is a plug-in that displays pop-up notifications with corresponding keyboard shortcuts whenever you use the mouse to execute a command. It also recommends creating shortcuts for frequently executed commands.

If you use one of the predefined keyboard mappings in your operating system, you can print the default keyboard mapping reference card and leave it on the desktop for review as needed. The cheat sheet can also be found under help | help. Keyboard mapping reference.

To print a non-default or custom keyboard mapping, use the keyboard mapping exporter plug-in.

Use advanced featur

You can use the following useful features to further increase productivity:

Quick list

If you often use a set of actions, create a quick list to access them using custom shortcuts. For example, you can try using the following predefined Quick list:

ReFactor the Ctrl+Alt+Shift+T

VCS operates Alt+ `

Smart key

IntelliJ IDEA provides many typing aids, such as automatically adding paired tags and quotation marks and detecting CamelHump words.

Speed search

When the focus is on a tool window with a tree, list, or table, start typing to see the match.

Press twice

Many operations in IntelliJ IDEA can provide more results when executed multiple times. For example, when you call the base code with a field, parameter, or part of a variable declaration, Ctrl+Space suggests a name based on the type of project in the current scope. If you call it again, it will include classes that are available through module dependencies. When the suggestion is called for the third time in a row, the suggestion list will include the entire project.

Resize the tool window

You can resize the tool window without the mouse:

To resize the vertical tool window, use Ctrl+Shift+Left and Ctrl+Shift+Right

To resize the horizontal tool window, use Ctrl+Shift+Up and Ctrl+Shift+Down
