There is an issue for me on my Mac with shortcuts

Shortcut for move left or right: cmd+[ or cmd+]
Shortcut for move up or down: alt+cmd+[ or alt+cmd+]

to get the [ or ] I need to hit: alt+5 or alt+6

→ you see the problem for alt+cmd+[? I should hit alt+alt+cmd+[ That is simply not possible
=> please make a change in the shortcuts for move up or down. Or have you an alternative way to handle that?

You’ll need to make a plugin to define your own shortcuts.

It is the case for many european keyboard maps. The [ and ] are not reachable without modification key.

Shortcuts that work everywhere ?
