patch 9.0.0887: cannot easily try out what codes various keys produce Commit: https://github.com/vim/vim/commit/a44c7811ff1c5519ac9acd6a34c58c98366f5c5f Author: Bram Moolenaar <Bram@vim.org> Date: Tue Nov 15 22:59:07 2022 +0000 patch 9.0.0887: cannot easily try out what codes various keys produce Problem: Cannot easily try out what codes various keys produce. Solution: Add a script to gather key code information, with an initial list of codes to compare with.
