I didn't know about kkp package. Need to try it out - especially on MacOS there are still performance issues (that I work on) so having workable terminal with all the keybinds available would be helpful.
By the way, recently Kitty introduced variable sized text, which probably could be integrated in Emacs, too, to have my favorite feature - font resize per frame :)
I can highly recommend KKP. It works very well in Kitty, and it even lets you map super keybindings, swap modifier keys, etc. I also used it on MacOS to get a low-latency frame on big hiDPI screens where the Cocoa GUI becomes quite unusable.
It also works fine in many other terminals like iTerm2 and Ghostty. Last I tried, they don’t report Super though.
