macOS Keyboard Utility
Modifiers,
redefined.
Tap a modifier. Hold one. Gesture with it. The keys you already press — now doing more than modify.
One app, four jobs
Window operations. App launcher. Input switcher. Enter Guard. The utilities you'd normally piece together from Magnet, Rectangle, Raycast, and Karabiner — as a single menu bar icon.
Keys you already hold.
New tricks.
Three ways Kanary turns your modifier row into a command surface.
Tap.
Single-press a modifier alone to fire a distinct command. Hold it normally and system shortcuts keep working.
Hold.
Bind any shortcut to any app. Launch it, summon it, or Quick Peek and it hides itself when you are done.
Gesture.
Hold modifiers and move the pointer to reposition, resize, or snap any window. No handles, no clicks.
Small app.
Big reach.
Move & Resize
Hold a modifier and move the pointer to reposition, resize, or snap a window — left, right, or maximized, then back. JIS users get Caps Lock to Control remap built in.
Launch & Hide
Map a shortcut to any app. Summon it when needed, hide it when done — perfect for dictionary or calculator apps. Less window juggling.
Switch & Set
Tap left or right ⌘ to flip between IMEs. For English-only apps, set a default input mode and Kanary switches to it automatically when the app becomes active.
For bilinguals
One tap.
Your language switches.
No JIS keyboard? Left ⌘ for alphanumeric, right ⌘ for kana. No need to know which mode you're in — just tap before you type.
Enter Guard
Enter breaks a line.
⌘Enter sends.
In AI chat apps, one stray Enter ships a half-written prompt — and with Japanese input, the Enter that confirms a conversion can send it. Enter Guard remaps the composer in native AI apps: Enter for a new line, ⌘Enter to send.
Works in the ChatGPT (Codex), Claude, Cursor, Gemini, and Perplexity desktop apps. Free for one app of your choice — Personal unlocks all of them. On the web, the Kanary Enter Guard browser extension has you covered.
The keyboard you already own.
Smarter. Stronger.
Free to download. Runs quietly in your menu bar.
