Fair enough, if they go with those banks they can’t be moved, it was the only thing that looked a little strange to me though, so thought I’d enquire.
I had only moved buttons, not added, I know you had given Shift/Ctrl/Alt/Undo in the latest upload, which I modified.
Ok, edited again and included another 4 keys:

with the buttons now I have used the whole space… 
let me know if I have to change the text/features on this new layout.
Here you can get a idea the new keyboard with the 18.5" multitouch display…:
Is amazing…
