I have removed the shortcut for SCI_DELETEBACK and as such my backspace key now outputs a backspace character rather than actually deleting characters.
For whatever reason, it's not possible to re-assign this key (probably because they've assumed no-one will be stupid enough to try and change it) so now I'm stuck.
Ideally I'd like to re-assign the backspace key to the SCI_DELETEBACK command but I think resetting the lot would be easier.
Prove me wrong!
Thanks
