Hi David and David, Thanks for your help with this! I took everything out of my config and started from scratch via customize. I believe I found my own configuration error this way - two of the saved searches may have had the same shortcut key of “I”. When I made them unique, naturally I was able to get both results, not just the first choice that didn’t have tree set. Oof. Thank you for the great program and for helping me blunder thru this debugging. On Fri, Jan 8, 2021 at 08:58 David Bremner wrote: > Jonathan Wilner writes: > > > Great idea.
