This was the missing piece! As silly as it may sound, the word "Variable" has intimidated me until my recent change of heart and new willingness to take on coding. As part of being intimidated, I've been avoiding doing or looking at anything with the word "variables" nearby. It was kinda like how the word "Voldemort" was treated in Harry Potter's world. An outcome of this is while I've read or scanned most of the basic materials including scanning thru all of KM's preferences MULTIPLE times, I was looking with a deliberate blind eye. The "Variable Preference Pane" had no meaning for me and I scurried by (throwing in a silent blessing and crossing myself for good measure) as quickly as possible without giving it a thought. Oh the things us unwashed, ignorant heathen do to get thru our wretched lives...
BTW searching for "KM Variables Panel" or just "Variables Panel" in the wiki doesn't get you there. You have to search for "Variable Preference Pane". A small tweak that allows the use of Pane or Panel would have helped this newbie.
Now that I'm on speaking terms with Mr. Variables I was free to do a search on the old man and found this coolness:
My coding world had gotten a bit bigger and brighter thanks to this exchange. Thank you for hanging in with this drama queen as I slowly pry these very stubborn old eyes open. I now have a new tool to follow your lead:
