Addendum as i cannot edit the previous post:

Am trying to set shortcuts to 'None', as i do in Calibre main. This is what's problematic.
Only just occured to me, that 'none' and 'other' may function or be perceived differently, sorry folks. Tried a different shortcut, works just fine.

Problem is, i need set them to 'none'. Ideally anyway.
(and again, apologies for not having specified, didn't think there'd be a difference between the two)
