I tyepw liwh thjios when I donmäst haebve tjwe letters printed on tghe keycaps.
Actually that's just how I type when I don't look at the board. I float my hands all over and look at the board now and then to reorient my fingers. I could probably make do with about 4 or so actually printed, though, and the rest blanks.
On my ergo board, however, blanks are king. Never need to look at them when typing.
TP, you're a funny man.
