Custom Shortcuts can be assigned to most functions in the target application that have a user interface like e.g. a Button. There are two ways to assign a custom shortcut:
1) Via Custom Shortcut Notifier
Custom Shortcuts can be assigned from within the Custom Shortcut Notification. The Custom Shortcut Notification appears if you click in the Button in the target application and if the operation has no shortcut assigned. They can be distinguished from normal Notifications from its color which is Magenta.
In the Custom Shortcut Notification, click the Shortcut Textfield and press the Keys on the keyboard for the shortcut you want to assign. Afterwards you can either press Enter or click the Save button.
2) Via Shortcut Browser
The KeyRocket Shortcut Browser can be opened by pressing Win+Shift+K. Actions that can be assigned to a Custom Shortcut show a small wrench beside. When clicked, a Shortcut Textfield opens. Click inside and press the Keys on the keyboard for the shortcut you want to assign. Afterwards finish by pressing Enter.
