TelunKey

TelunKey is a native macOS keyboard window switching tool developed in Swift.

Designed for work scenarios that frequently switch between multiple applications, windows, and the desktop. It integrates application activation and target window selection into a single keystroke. The software supports independent triggering of the left and right Command keys, the left and right Option keys, and also allows triggering via Space, enabling users to customize the operation according to their preferences. Upon triggering, the actionable target is immediately displayed, and the window is mapped to the key area according to the keyboard layout. TelunKey Users can confirm the target simply by pressing a key, reducing the need to repeatedly switch applications and search for windows with the mouse. This is especially suitable for scenarios involving multiple windows in Chrome and concurrent operation of numerous windows. TelunKey prioritizes low-latency response and lightweight background operation, reducing redundant calculations and unnecessary wake-ups by updating window information on demand and using lightweight caching. Core data is stored locally, and by default, no behavioral analysis is performed, nor does it rely on cloud services. The software requires at least macOS 14.0 Sonoma and can be installed and updated via Homebrew, or by checking for updates within the application. Accessibility permissions are required for first-time use, and screen recording permissions are required to display window thumbnails.
