I cut/paste for very minute adjustoments.
Pay attaention to From-Thru
If From-Thru says 3-2-4456 thru 8-3-244 and I want to move it three ticks, I cut it and paste it at 3-2-4459.
This is where resolution becomes important.

If you set your Options-Resoltuion to the max you can often get down to smaller than milliseconds.

60,000 millisends per second
at Tempo 120 there are 500 milliseconds per beat.
At resolution 3920 each tick division is .128 milliseconds per tick
Providing my maths are good.

I do not work here, but the benefits are still awesome
