Left-handed comfort for any Mac keyboard
LeftyKeys swaps CapsLock⇄Enter and Tab⇄Backspace system-wide, so left-handed typists reach Enter and Backspace without stretching across the board. A quiet menu-bar app — no hardware, no remapping config, no permanent changes to your Mac.
Key Features
CapsLock ⇄ Enter and Tab ⇄ Backspace, applied everywhere — every app, every text field, no exceptions.
Want only CapsLock ⇄ Enter, or only Tab ⇄ Backspace? Flip each swap on or off on its own from the menu bar.
No Dock icon, no windows in your way. One menu-bar icon shows at a glance whether your swaps are active or paused.
Turn on launch-at-login and LeftyKeys is armed the moment you sign in — no relaunching after a reboot.
LeftyKeys makes zero lasting changes to macOS. Quit the app and every key instantly returns to its default.
Runs natively on Intel and Apple silicon, macOS 13 and later. No telemetry, no analytics, no account required.
Why We Built This
Keyboards are built for right hands. We fixed that in software.
Every hardware keyboard puts Enter and Backspace on the far right — a daily stretch if you lead with your left hand. Meanwhile CapsLock and Tab, keys most people rarely lean on, sit in the best real estate on the left. LeftyKeys simply trades them: CapsLock becomes Enter, Tab becomes Backspace, system-wide, in every app. No hardware to buy, no layout to relearn, no config file to babysit. It installs in under a minute, runs silently from the menu bar, and makes no permanent changes — quit the app and your keyboard is exactly as it was. Built for left-handed writers, developers, and students who just want their keyboard to stop fighting them.
That's hundreds of millions of typists using a keyboard laid out for the other hand. LeftyKeys quietly evens the odds.
Most people hit it by accident more often than on purpose — which makes it perfect real estate to reclaim for Enter.
LeftyKeys never rewrites your system settings. It swaps keys live, so quitting the app restores every default immediately.
