These shortcuts were in PowerSDR from FlexRadio. Shortcuts are transferred to all modifications of the program (PowerSDR > PowerSDR mRX > Tethis).

Yes, that's right.
But the full list is much longer. Probably need a help button for shortcuts.

The keyboard shortcuts change Width and Shift very slowly . After releasing the keys, the change continues further. It slows down.
Width - Ctrl+F and Alt+F.
Shift - K and L.

A great idea.

Many thanks!

Please restore the functionality of the hotkeys back. Setup > Keyboard.
