Summary

This PR enhances the dotfiles with significant improvements to tmux workflow, a complete cheatsheet TUI rewrite, and adds lazygit + delta integration.

tmux Enhancements

  • Vim-style copy mode: prefix+Escape to enter, v to select, y to yank
  • Quick window toggle: prefix+a alternates between last two windows
  • Floating popups: prefix+p (ephemeral shell), prefix+P (command prompt), prefix+t (persistent scratch)
  • Pane management: prefix+J/S/B for join/send/break operations
  • Faster escape: Reduced escape-time from 500ms to 10ms

Cheatsheet TUI

  • Complete rewrite with Catppuccin Mocha theme
  • 4 organized sections: Alacritty, Tmux, Claude CLI, Vim
  • Global search with fzf (/ key)
  • Vim mode navigation with Escape (uses less)
  • Two-column layout with detailed descriptions
  • Responsive 112x90% popup

New Tools

  • lazygit: TUI for Git with Catppuccin theme
  • delta: Beautiful side-by-side diffs with syntax highlighting

Cross-Platform Compatibility

Feature Linux WSL macOS
tmux clipboard xclip xclip pbcopy
cheatsheet clipboard xclip/xsel clip.exe pbcopy
lazygit install GitHub release GitHub release brew
delta install GitHub release GitHub release brew

Test Plan

  • Test tmux copy mode on Linux (prefix+Escape, select with v, yank with y)
  • Test floating popups (prefix+p, prefix+t)
  • Test cheatsheet navigation and search (prefix+h, then / to search)
  • Verify clipboard works on each platform
  • Run ./install.sh --dry-run on target platform
  • Test lazygit opens correctly (lazygit or lg alias)
  • Verify delta diffs work (git diff)
