Hello,
thanks for the feedback, I accidentally found this email in my spam folder
🙁, so sorry for the delay with replying.
Tab is not a good choice for shortcut key because many widget toolkits use this key to change focus from one widget to another.
When using Tab together with "Shift" I guess there exists one moment when either Tab or Shift is being pressed alone, causing focus change (so that might cause issues).
Anyway, will test this later, thanks!
Note that there already exist a default hardcoded shortcut for the same action: Shift+Right arrow.
(similar shortcuts for move left, up, down - just use Shift + different arrow).
Regards,
Miro
