Note input and edit functions inquiry

Hi there,
Just wondering how to let selected notes an octave up or down? I’ve tried to customised key commands as shortcuts for this function, but they don’t work.
Also is there a function that notes can be mirrored or reversed?

To move notes up an octave, use Ctrl-Alt-Up on Windows, or cmd-alt-Up on macOS.

There’s no functions for inversion or retrograde operations, yet.
