Android Studio Shortcuts (Mac)

Notes:

• Two of the most useful shortcuts utilize the Fn (function) keys. It is therefore recommended that you enable the "Use all F1, F2, etc. keys as standard function keys" option [System Preferences > Keyboard].
• Be sure to enable the Mac OS X 10.5+ keymap in Android Studio [Preferences > Keymap].
• A fairly complete shortcut list can be found here.
