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, click File > Settings > Keymap (on Mac, File > Properties > Keymap).
Figure 1. The Android Studio keymap settings window.
- Keymaps dropdown: Delect 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.
