There are several crashes reported from firstRectForCharacterRange: which indicate that the system may ask for indexes “out of range”, hence why we now effectively just cap such request.
This means pressing e.g. ⌘/ (using the slash on the numeric keypad) will still work to toggle comments.
It also means that we can no longer bind specifically to the numeric keypad keys, but I don’t think anyone actually does that (given that few have numeric keypads).
The ideal solution would be to first do a literal check and then, if there was no match and the key event had the numeric keypad flag set, do a test with this flag removed, but that would change the simple string compare we presently use plus the easy caching and binary search of finding the item that matches a key event, i.e. it would add complexity to the code with no known argument in favor of this flexibility.
