Summary

  • Add Kitty-specific tmux settings: true color (RGB), extended keyboard protocol, graphics passthrough, OSC 52 clipboard, and focus events
  • Set escape-time to 10ms to prevent swallowed escape sequences
  • Add undercurl and colored underline terminal overrides

Changes

  • .tmux.conf: Added Kitty terminal optimization block between mouse/drag bindings and OS detection section

Test Plan

  • Reload tmux config (tmux source ~/.tmux.conf)
  • Verify true color: printf "\x1b[38;2;255;100;0mTRUECOLOR\x1b[0m\n"
  • Verify extended keys work in Claude Code (all keybindings respond)
  • Verify undercurl renders in nvim (:hi SpellBad gui=undercurl)
  • Verify clipboard: yank in tmux copy-mode pastes to system clipboard

Review Checklist

  • No secrets committed
  • No unnecessary file changes
  • Commit messages are descriptive

Clipboard chain now tries wl-copy first on Linux, falls back to
xclip/clip.exe for X11/WSL2 compatibility.
