That does not work for me as I would need to type a semicolon ; (instead of the comma) to separate the values and it involves using Ctrl as a mod key. For the same reason, I cannot move either to relative or absolute co-ordinates. The SU Team did not think of things like this when designing SU. About 2/3 of the world's population cannot use these commands I would risk to say.

cool feature, thanks a lot
