Small Multi-Trim/Extend Tip

Basic but never fully grasped or utilized this command in Revit.  Usually it was because I was detailing at the end and was in a hurry either way...

Did you realize that once you initiate the multi trim/extend command you can choose multiple cutting lines?

For example you pick a line and trim 3 that cross it.  Now you have to do the same thing for a perpindicular condition.  Instead of cancelling out of the command, click into white space on the screen.   Then choose the line you want to cut w/ and get started again. 

Pics later, but wanted to write it down while it was on my mind. Can eliminate several commands this way, so hey, free money.
