weird how so many people actually use right shift, though.
ermm.. ok, actually, i use it too, i just realized. while typing this. what i thought was "right alt" but my brain said "yeah, right shift, close enough, say you don't use it".
i use it only for @, :, " and ?, instead using left shift for the two < and >.
Originally i used it for even less, just the small cluster next to right shift, while using left shift for the number keys, which evolved in going up the numbers row while still using shift.
I also hold my left hand in a specific way, with the pinky touching the ~ key (left of 1) while typing, and holding Tab while gaming. Palm of the hand holds the left corner of the keyboard; due to having grown up with crap keyboards, i grip it like this to hold it still.
