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?
