Why is It Easy to Change From One Unit to Another in the Si System Html Editor Keyboard Shortcuts
Android Studio includes keyboard shortcuts for many common actions. Table 1 shows the default keyboard shortcuts by operating system. Keep in mind, because Android Studio is based on IntelliJ IDEA, you can find additional shortcuts in the IntelliJ IDEA keymap reference documentation.
Note: In addition to the default keymaps in table 1 below, you can select from a number of preset keymaps or create a custom keymap. For more about customizing your keyboard shortcuts, see Configure Custom Keymaps, below.

Configure custom keymaps
You can choose from a number of preset keymaps or modify a preset keymap to create a new custom keymap in the keymap settings for Android Studio.
To open the keymap settings, choose File > Settings (on Mac, Android Studio > Preferences) and navigate to the Keymap pane.
Figure 1. The Android Studio keymap settings window.
- Keymaps dropdown: Select the desired keymap from this menu to switch between preset keymaps.
- Actions list: Right click on 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 will automatically create a copy of the keymap and add your modifications to the copy.
- Copy button: Select a keymap from the dropdown menu to use as a starting point, and click Copy to create a new custom keymap. You can modify the keymap name and shortcuts.
- Reset button: Select a keymap from the dropdown menu and click Reset to revert it to its original configuration.
- Search box: Type here to search for a keyboard shortcut by the action name.
- Search by Shortcut: Click Find Actions by Shortcut and type a shortcut to search for actions by shortcut.
