[Sethomas]

Okay, my first reaction was to say something referencing the fact that the design of keyboards is centered around the idea that individual keys need to be "hit" for them to work in pretty much any conventional/intended use. Like, say, I could play on that idea with the suggestion that you have telekinetic powers that are useless on the M and B keys and the space bar because they, as you mention, are broken.

The problem is this would be very inconsistent with my character as you all know, since Sethomas would distinguish between the generalized act of "hitting" keys and the verb "depress" which would be more precise in this context.
