We can assign actions to perform when a particular input event occurs using the Add button beneath the action list in the Alt Controller profile editor.
This opens the Edit action window.
Select the type of action you wish to add and specify the details for it in the Settings panel. The above example shows an action that will type the key combination Ctrl+A.
See Types of action for information on the actions that Alt Controller can perform.
When you are done, click OK to confirm.
