Also, am I missing something or does the G13 limit you to 25 keys? Is there some key modifier (e.g., "alt") that can be used to double or triple the keys while using all on one hand?

As an example, I have a lot of "left side" keyboard stuff set up so I can use my left hand exclusively to modify a keystroke. (i.e., alt-1) So, I'm probably pretty close to 25, single-left-hand commands just using my keyboard. Seems the G13 would be real limiting versus the G11 keyboard that would give me another 18 keys (no mod) and up to 36 more (54 total) with a mod that I might even be able to do with just my left hand?
