GoTo previous NowTime

Not sure if possible with a "CAL thing"
Would be nice to have a "GoTo previous NowTime"
 
That way if you accidentally hit Pause (which moved NowTime from where you wanted to be working) you would still have a shortcut to go back to that previous NowTime.
 
And would like the opposite also.
If I accidentally hit "Stop and return to NowTime" (instead of pause), I would like a shortcut to "GoTo last stop point".
 
These two shortcuts would nicely speed up my workflow.
 
OR it could be a key that just corrects (and does the opposite) of what you just did. Feature would be called "I meant the other way to stop".
