You could use AutoHotKey. I'm not sure if it works on OS other than Windoze, but it can be used to remap all of your keys, and you can even map a key to "Pause", which makes the software temporarily inactive (and thus you are able to type normaly) until the next time you click it.
Ofcourse, this is only a workaround, a patch allowing remapping will be better.
