patch 9.0.0930: cannot debug the Kitty keyboard protocol with TermDebug Commit: https://github.com/vim/vim/commit/63a2e360cca2c70ab0a85d14771d3259d4b3aafa Author: Bram Moolenaar <Bram@vim.org> Date: Wed Nov 23 20:20:18 2022 +0000 patch 9.0.0930: cannot debug the Kitty keyboard protocol with TermDebug Problem: Cannot debug the Kitty keyboard protocol with TermDebug. Solution: Add Kitty keyboard protocol support to the libvterm fork. Recognize the escape sequences that the protocol generates. Add the 'keyprotocol' option to allow the user to specify for which terminal what protocol is to be used, instead of hard-coding this. Add recognizing the kitty keyboard protocol status.
