I have a number of projects with long lists where I'm trying to look at or operate on some subset of the long list but would like to keep the column titles visible.

The problem is if I split the screen and/or freeze panes with titles, I can't figure out how, if it is possible, to split the screen below a second time for looking at or conveniently selecting a group that starts at say line 3318 and goes to line 9965.

This would be more equivalent to print titles metaphorically speaking.

thanks,

brian
