Tmux Cheatsheet

A tiny, native macOS app: a searchable, click-to-copy reference of tmux shortcuts.

---

Pure reference — it does not control tmux, run any processes, or touch other apps — so it's fully sandboxed and Mac App Store-eligible.

It's a standalone companion to Tmux Kit (the full GUI manager), but shares no code or data with it — the two are independent projects.

Usage

• Filter as you type to find a shortcut by name, keys, section, or note.
• Click a row to copy its key sequence to the clipboard.
• Summon from anywhere with the global hotkey — default ⌘⌃⌥⇧C (Hyper+C). Press it again to hide. Rebind it in Settings (⌘,).

Screenshots

Build

# prerequisites: Xcode, XcodeGen (brew install xcodegen)
xcodegen generate
open TmuxCheatsheet.xcodeproj      # or: xcodebuild -scheme TmuxCheatsheet build

The app icon is generated by scripts/make-icon.swift (a keycap with a ? — tmux's prefix ? lists all key bindings).

App Store

Sandboxed and submission-ready. Shipping it requires an Apple Developer Program membership and an App Store Connect record (created under your own Apple account).
