Important Keyboard shortcuts in Android Studio

Shortcuts are increase programming speed. It's increase the well style coding format and other features.

Keyboard shortcuts are a useful way of quickly navigating around Android Studio and performing common actions. In many cases, using keyboard shortcuts is faster than using the GUI.

Tool windows

You can use keyboard shortcuts to open tool windows. Table 1 lists the shortcuts for the most common windows.

Table 1. Keyboard shortcuts for common tool windows

Tool window	Windows and Linux	macOS
Project	Alt+1	Command+1
Version Control	Alt+9	Command+9
Run	Shift+F10	Control+R
Debug	Shift+F9	Control+D
Logcat	Alt+6	Command+6
Return to Editor	Esc	Esc
Hide All Tool Windows	Control+Shift+F12	Command+Shift+F12

Code completion

Android Studio has three types of code completion, which you can access using keyboard shortcuts, as shown in the following table.

Table 2. Keyboard shortcuts for code completion

Type	Description	Windows and Linux	macOS
Basic Completion	Displays basic suggestions for variables, types, methods, expressions, and so on. If you call basic completion twice in a row, you see more results, including private members and non-imported static members.	Control+Space	Control+Space
Smart Completion	Displays relevant options based on the context. Smart completion takes into account the expected type and data flows. If you call Smart Completion twice in a row, you see more results, including chains.	Control+Shift+Space	Control+Shift+Space
Statement Completion	Completes the current statement, adding missing parentheses, brackets, braces, formatting, and so on.	Control+Shift+Enter	Command+Shift+Enter

To perform quick fixes and show intention actions, press Alt+Enter.

Navigation

Use the following tips to help navigate around Android Studio:

• Switch between your recently accessed files using the Recent Files action. To bring up the Recent Files action, press Control+E (Command+E on macOS). By default, the last accessed file is selected. You can also access any tool window through the left column in this action.
• View the structure of the current file using the File Structure action. To bring up the File Structure action, press Control+F12 (Command+F12 on macOS). Using this action, you can quickly navigate to any part of your current file.

• Search for and navigate to a specific class in your project using the Navigate to Class action. To bring up the Navigate to Class action, press Control+N (Command+O on macOS).

  Navigate to Class supports sophisticated expressions, including camel humps (which lets you search by the capitalized letters in an element's camel-cased name), paths, line navigate to (which lets you navigate to a specific line within the file), and middle name matching (which lets you search for a part of the class name). If you call it twice in a row, it shows you the results out of the project classes.

• Navigate to a file or folder using the Navigate to File action. To bring up the Navigate to File, press Control+Shift+N (Command+Shift+O on macOS). To search for folders rather than files, add a / at the end of your expression.

• Navigate to a method or field by name using the Navigate to Symbol action. To bring up the Navigate to Symbol action, press Control+Alt+Shift+N (Command+Option+O on macOS).

• To find all the pieces of code referencing the class, method, field, parameter, or statement at the current cursor position, press Alt+F7 (Option+F7 on macOS).

Default keymaps

Android Studio includes keyboard shortcuts for many common actions. Table 3 shows the default keyboard shortcuts by operating system.

Note: In addition to the default keymaps in table 3, you can select from a number of preset keymaps or create a custom keymap. For more about customizing your keyboard shortcuts, see the Configure custom keymaps section.

Configure custom keymaps

The keymap settings in Android Studio let you choose from a list of preset options or create a custom keymap.

To open the keymap settings, choose File > Settings (on macOS, Android Studio > Preferences) and navigate to the Keymap pane.

Figure 1. The Android Studio keymap settings window on macOS.

1. Keymaps menu: Select the desired keymap from this menu to switch between preset keymaps.
2. Actions list: Right-click an action to modify it. You can add additional keyboard shortcuts for the action, add mouse shortcuts to associate an action with a mouse click, or remove current shortcuts. If you are using a preset keymap, modifying an action’s shortcuts automatically creates a copy of the keymap and adds your modifications to the copy.
3. Copy button: Select a keymap from the menu to use as a starting point, and click Copy to create a new custom keymap. You can then modify the keymap name and shortcuts.
4. Reset button: Select a keymap from the menu and click Reset to revert it to its original configuration.
5. Search box: Type here to search for a keyboard shortcut by the action name.
6. Search by Shortcut: Click this button and type a shortcut to search for actions by their assigned shortcut.
