Changing an ASCII character operand back to default was going through a path that tried to resolve low vs. high ASCII, which isn't useful when you're removing the item. The root of the problem was that the "default" button wasn't properly resetting the UI. Also, updated keyboard shortcuts to be in sync with the instruction operand editor.
