[Bug]: No (obvious) way to remove a keyboard hotkey?

[spex66]

Description

Switching from Windows to Mac I'm happy to get Zoomit :)
But a very simple issue:
How to remove/disable a keyboard hotkey?

Reason for asking: I don't need all but typically ctrl-2 for screen annotations only, and want to minimize collisions with other apps.

Current Behavior

Open settings, and clicking the hotkey, I only figured out how to set another hotkey, but not how to disable/remove it.

Expected Behavior

Add a hint in the setting-form, that i.e. "backspace" -- like on Windows ZoomIt -- is setting it to "None"

Steps to Reproduce

1. open ZoomIt Settings
2. click into "Zoom Toggle" to change the hotkey
3. click "Backspace" which is not disabling it (setting to "None")
