Funny to hear this, because I have that Matias keyboard and never ever use those dedicated undo/cut/copy/paste keys, because I feel there's no point retraining myself to get used to their placement (in a column on the far left of the board) when they're never going to be on my laptop keyboards too.

AFAIK those keys send the equivalent of the literal key chord (e.g. Cmd-Z) to the computer. I wish I could flip a switch and have them be considered keys in their own right, maybe F13-F16.
