Hello.
Some DAWs support shorcuts to move playhead by quantize value.
(Cubase - Nudge Cursor Left and Right)
This feature looks very simple, but it is very useful and make works efficient as we know.
of course we can do same thing by using mouse, but 'using keyboard' is speedy and it is hard to cause carpal tunnel syndrome compare to using mouse for some users. (I'm the one.)
Thanks.
