MicKey

MicKey is a small standalone Windows utility to toggle the microphone system-wide using a shortcut.

Usage

Download the application from the GitHub releases and run it.

It will appear in the system tray:

Muted	Unmuted

Click the tray icon to show the main window, or right click the tray icon to exit the application.

Muted	Unmuted

Here you can set the global hotkey, which works even if the application is minimized, or toggle the mute.

The window will always show itself on top of other windows, as it is intended to be used as an indicator to see whether the microphone is currently muted or not. You can close the window to return it to the tray, or minimize it to keep the task bar indicator:

Muted	Unmuted

Tip: By default the hotkey is set to F24, which most keyboards tend not to have. It may be useful to bind this key to your mouse buttons!

Automatically launch on startup

To automatically launch this program on startup:

1. Press Win+R to open the Run dialog and type shell:startup then press enter

2. Right click in the resulting folder and choose New -> Shortcut

3. Make a shortcut to your MicKey.exe
