I am on a lot of calls for work every day and juggle several different call applications. Finding the apps mute/unmute button quickly gets tedious. On some apps the UI is so poorly designed as to make toggling the mic nearly unusable.
Enter Alfred! Alfred is an amazing productivity app. Alfred let you run custom commands and hotkeys in custom Workflows.
I created a Workflow that, once installed, allows you to mute and unmute your mic with the command-M hotkey.
To install simply download the Workflow and double click it to load it into Alfred.
The Workflow is on Github! If you have ideas for improvements create a fork and send them to me: https://github.com/blobaugh/Mic-PTT-Alfred-Workflow
