About "Key Rotation"

Key Rotation allows you to register up to 10 shortcut keys.
※ Only single-action keys on the keyboard can be registered.

If you register a single shortcut key (such as V : Selection Tool, H : Hand Tool, P : Pen Tool, I : Dropper Tool etc. in Illustrator), you can call it up in rotation.

This can be useful when you want to call up several different shortcut keys with the same operation as much as possible.
