Special keymap re-assignment for file collections

Was hoping an option could be provided to change the delete key behaviour specifically in File Collections so that when pressed it perofrms the 'Delete REMOVECOLLECTION' function instead of regular delete, and reassign 'real' delete to an alternate like Shift-Delete or something. I know a button can do this, but I just ALWAYS find myself going for that Delete key... and when I do really want to delete the actual file, I'd rather not receive the warning advising that the 'real file will be deleted...' etc etc. The way it is now though I 'need' the warning cuz I keep going for the delete key... ah!
