Terminal Stack Research 2026

1 — tmux Prefix Key

2 — Pane Navigation: smart-splits.nvim

3 — Claude Code Popup Pattern

bind C-c display-popup -d "#{pane_current_path}" -xC -yC -w 80% -h 80% -E \
  "tmux new-session -A -s claude 'claude'"

Prefix + Ctrl-c → popup opens → dismiss → session persists in background.

4 — Escape Delay Fix (zsh-vi-mode + tmux)

set -sg escape-time 0

# ~/.zshrc
export KEYTIMEOUT=1
ZVM_READKEY_ENGINE=$ZVM_READKEY_ENGINE_NEX
# Fix fzf Ctrl-R conflict
zvm_after_init_commands+=(
  '[ -f ~/.fzf.zsh ] && source ~/.fzf.zsh'
)
