IFF - keybindings for "set M1 code" and "set M3 code"

[Retnek]

There's a problem setting the "set M1 code" and "set M3 code" counters via the keyboard. Clicking them up and down via the mouse is fine and need 8 clicks for each passage. Setting  a key-combo "rshift + rwin + x" for the action "IFF Mode 3 Code Digit 1 - [Next]" f.e. results in a wrong stepping - it's just 7 klicks from "zero" to "zero" again.
It's ok for "... [CCW]" and "...[CW]", but via keyboard the "...[Next]"-actions miss one step for the the two M1- and four M3-mode-dialers.
