Key Commands allows you to invoke Activator actions using simple keyboard shortcuts. It puts the full power of Activator at your fingertips. Create your own shortcuts in System Preferences and then assign them to actions. For example, assign ⌘-Tab to navigate to the previous app. Or ⇧-⌥-T (Shift-Option-T) to compose a tweet. The possibilities are endless.
Note: Due to the limitations of iOS's event handling, a select few keyboard shortcuts are not assignable. For example, ⌘-⌫ (Command-Delete) cannot be used. Also, several shortcuts starting with ^-⌘ (Control-Command) are unassignable. Aside from these few, however, you can create any shortcuts you want!
