✨ Remove trigger key restriction, assign any keybinds to any actions

[Ender-Wang]

Feature Request Description

• Recently I changed my trigger key from global key to (right) opt key, cause I found that I need to use two hands to set window snapping when trigger key is the global key.
• Now I can easily snap window by one hand, but then I found I still need to hands to do certain things, so it's kinda limited if the trigger key is hard set to one key, it would be much better if we could just drop the trigger key, instead set keybinds to actions directly.
