I am not so sure about the proposed layout. It will not be as easy to find the arrow keys by touch as before. The space in-between the keys provides a guide for the fingers.
I like it. I'm still thinking of how I will arrange the arrow keys for my 180-flip-thumbs-on-f-keys mod.
I have been thinking about a minimalistic ergo layout with thumb keys ... I am leaning towards using
Fn-key (left thumb) +
IJKL as arrow keys, with
Home/
End/
PgUp/
PgDn around them as on a numpad. The "home row" for a nav cluster is where
Left-
Down-
Right is, so it is natural that if the alphabetic keyboard would be overloaded with arrows, those keys would go onto the alphabetic home row.
This has also a lot to do with me having come accustomed to the numpad on my G80-1800s.
But I am not entirely content with that. I have also been thinking of having arrow keys where the
Right Shift key is and letting the other nav keys be combinations of
Fn-arrow, but they I would have to move the
In either case, I think that
Insert belongs on
Fn-
Delete ... :-P
