Keyboard input in Editor but not KeyCode

Hi! Since char type is not shown in the inspector, I’m trying to get it through keyboard input. First problem is KeyCode contains values like ‘Underscore’ instead of ‘'. The second - it seems like some keys (like Shift) can’t be used in a custom editor. So how do I get the '’ (Shift + Minus) instead of ‘Minus’? Thanks!

That might require a nifty custom editor mixed with EnumMaskField attribute if you want to use multiple keys.

There has been a post that isn’t specific to what exists for the input inspector, but if you created your own script for managing the keyboard input you could select multiple keys.
