I was finally back on task and needed to tie in to an EOP in a reference model. Once in the command, after identifying the need to use a Corridor Point point control heads up display, and selecting the corridor from the list, I was able to graphically pick a corridor point/line and did not have to know its name. I was able to hover over the corridor to get its name - but it might be possible to select the corridor graphically, too.
That will be a test for another day.
