Thank you, Pils. Very much appreciated!
I searched the OpRef manual for “circle” and “encircled” but came up no joy. Looks like searching on “symbol” would have been a good bet.
My follow-up search was going to be what do the SF, RD, and CR acronyms that I see mean. Had I done that I might have found the answer you provided.
I’m continuing to study this study level wonder by reading the included docs and following the checklists.
Thanks for your help here in the forum and in the Discord.
