Reset All Shape Keys Hotkey
The button does nothing when I'm in any mode other than Object Mode, why?
Due to how Blender handles shape keys, you can only change their values from the Object Mode. This limitation is on Blender's side.
How do I install this addon?
Simply place it in a folder that you won't move, then go to Blender -> Preference -> Add-Ons -> Install, then find this addon in the browser window, enable it and you're good to go!
Where do I find the new buttons?
You can find them in the 'Tool' tab in the last section.
How do I hotkey the buttons?
Simply right click either button and press on 'Assign Hotkey'. Then press any key combination you want.
They hotkey I assigned does not work, what do I do?
The hotkey you pressed is probably used somewhere else. You can check that in the Keybinds category in settings.
