I played with this a little and found that in the SwordSearcher editor, you can copy a red pg once, then use Ctrl F to find the next occurrence of pg, close the Find dialog box (which leaves the pg highlighted), Ctrl V to paste the red pg, Ctrl F to find the next occurrence, close the Find dialog box, Ctrl V, repeat. It could be a little tedious if you have many, but the Find dialog will retain the "pg" so you don't have to type that in each time, and with the F and V so close together, you can easily use your left hand for Ctrl F or V, and your right hand can click either 'find' or 'cancel' - you get into a rhythm ([left hand] Ctrl V, Ctrl F, [right hand] Find, Cancel) and it actually goes pretty fast.
I agree with you - SwordSearcher is by far my favorite Bible program, too! There are so many features and options that it quickly becomes a uniquely personal tool.
