Hotkeys for tools palette

Hey,

I am just starting to explore Imagine and shape and was wondering if there is a possibility to assign a hotkey to any of the items in tools palette. I was already looking through Customize -> all commands but it's missing all of the commands I need, namely I would like to assign vertex select to "1" on keyboard.

I already saw that there is a shortcut assigned to it but it's a bit clumsy and since you can see the actual command in bottom right "c:IMA_Select vertex" I was wondering if it's possible to assign a hotkey to that command instead?

Thanks
