I am the author of iTerm2. A user reported that Shift-F2 (and other shift+function key combos) did not work.
Using mc's "Options > Learn Keys" feature, I can see that when I press Shift+F2 it is recognized as F12. I have a completely stock configuration. This is on macOS.
I verified that iTerm2 correctly sends \e[1;2Q when you press Shift+F2. I was able to reproduce the same problem in xterm, Kitty, and Alacritty. The built-in macOS Terminal does not seem to support shift+function keys at all. My $TERM is set to xterm-256color. infocmp -x gives kf2=\EOQ but as far as I know terminfo isn't very useful for function keys combined with modifiers like shift (I could be wrong about this).
I searched the issues and found some very old ones about shift+function key having other problems. I'm sure there's a lot of history here! I would love to help fix this problem whether from my end (if it's a bug in iTerm2) or yours.
