The following error may appear when starting Clibor:
Failed to register the hotkey.
By default, Clibor uses the Ctrl key as a hotkey when it starts.
This error occurs if another application is already using the Ctrl key as a hotkey.
(For example, an app that is triggered by pressing Ctrl twice, similar to Clibor.)
In that case, the hotkey is set to None. Open Preferences and assign a different hotkey.
