Corner TaskView

Electron tray helper for Windows that triggers Win + Tab (Task View) when your cursor touches a configurable screen corner.

Prerequisites

• Node.js 18 or newer
• Windows 11

Development setup

npm install
npm start

The app does not open a window. A tray icon appears instead. Right-click the icon to choose:

• the corner to watch
• the target display
• the detection speed (Instant, Very fast, Fast, Medium, Slow)

The detection speed controls both the pointer polling frequency and the cooldown before the next Win + Tab trigger. The “Instant” preset runs an immediate loop for the lowest latency. The shortcut fires only once per entry into the corner until the pointer leaves it.

Configuration

• Tray icon: replace icon.png at the project root to ship a custom icon.
• Corner threshold: tweak the EDGE_THRESHOLD_PX constant in src/main.js to widen or tighten the hot corner area (default 30 pixels).
• Preferences are stored via electron-store in the user profile (corner, displayId, detectionSpeed).

Build a Windows installer (NSIS)

The project is configured for electron-builder.

npm run dist

The installer is generated under dist/. It uses NSIS with:

• directory selection (not one-click)
• optional desktop shortcut
• optional “launch on Windows startup” toggle (writes to HKCU Run)

The uninstaller cleans up the desktop shortcut and startup entry that the installer created.
