I did get it working. My God, the amount of power that I don’t know about in this app. Please don’t increase the price on me next week, Autodesk! (Unless you give me fluids in Maya complete!) 
To get this working, I selected an edge. If you hold ctrl and right click, extra options appear- at about 5 o’clock there is an option called “edge loop utilities”, which opens futher menus like to “to edge loop” and “to edge loop, then delete”, etc.
Now- to get there quicker- if you can memorize all this stuff, you select an edge, hold ctrl, and QUICKLY right-click and drag down further and faster into the five o’clock position. I had more luck by dragging my mouse faster and a greater distance than I normally do in marking menus.
This takes you directly into “edge loop utilities” and the options it would normally require two gestures to get to.
goleafsgo - great tip!
