Overview
A tiny native macOS app (~600 lines of Swift) that binds any two keys to hide the frontmost window or open a fast app switcher. Designed for the 英数 and かな keys on a JIS keyboard — they sit under your thumbs and clash with nothing. Configurable for ANSI too.
“Replaces a fragile Karabiner + AltTab combo that flickered constantly on macOS Tahoe. One process, no synthetic events, no flicker.”
What it does
- Hide / minimize the frontmost app — windowed or fullscreen
- Fast app switcher: tap to advance, Enter to commit
- Single-process design (no flicker like Karabiner + AltTab)
- JSON-configurable bindings
