There is currently only one keyboard shortcut that can be configured via Hook itself: “Show Hook window” described in the next section.
Configurable shortcut: Show Hook window
The default shortcut for this is ⇧⌘SPACEBAR. That is: spacebar key while holding the shift and ⌘ keys down together at the same time.
You can assign a global hotkey or key combination with which to invoke the Hook window. This will override any other application which uses the same keys, so choose keys which won’t conflict with anything important. If you uncheck the box it will disable the hotkey.
