Jump the text cursor into any input field on screen, keyboard-only,
in the spirit of VSCode's Jumpy, but system-wide.

Press ⌃⌥J and Jamb walks every window visible on screen, all apps, not just the active one, through the Accessibility API, finds every visible text input (fields, text areas, search fields, combo boxes, never password fields), and overlays each one with a short label chip. Type a chip's letters and the caret lands at the end of that field's text, ready for typing, activating that app first if the field lives in a background window. Escape or a click anywhere dismisses.

Status

Prototype. Current scope is field-level jumping (caret to end of text) across the windows of the current Space. The fuller Jumpy treatment, labels at word positions inside each field via AXBoundsForRange, is the planned next step.

Browsers

Web-page inputs work once the browser exposes its web-content accessibility tree:

• Safari/WebKit exposes it by default, no setup.
• Chromium (Chrome, Brave, …) keeps it dormant, and no external signal wakes it (AXManualAccessibility is Electron-only; modern Chromium ignores AXEnhancedUserInterface). Enable it in the browser itself: on chrome://accessibility / brave://accessibility check BOTH “Native accessibility API support” AND “Web accessibility” (they are separate mode bits; one alone does nothing), then reload the tab. For a permanent switch launch with --force-renderer-accessibility.
• Electron apps wake theirs via AXManualAccessibility, which Jamb sends automatically.

Requirements

Jamb is built on the Accessibility API, so macOS will prompt for Accessibility access on first launch (System Settings → Privacy & Security → Accessibility). Until granted, the hotkey just beeps.

Development

swift run Jamb   # requires granting Accessibility to the built binary
swift test
