+--- === PushToTalk ===
+---
+--- Implements push-to-talk and push-to-mute functionality with `fn` key.
+--- I implemented this after reading Gitlab remote handbook https://about.gitlab.com/handbook/communication/ about Shush utility.
+---
+--- My workflow:
+---
+--- When Zoom starts, PushToTalk automatically changes mic state from `default`
+--- to `push-to-talk`, so I need to press `fn` key to unmute myself and speak.
+--- If I need to actively chat in group meeting or it's one-on-one meeting,
+--- I'm switching to `push-to-mute` state, so mic will be unmute by default and `fn` key mutes it.
+---
+--- PushToTalk has menubar with colorful icons so you can easily see current mic state.
+---
+--- Sample config: `spoon.SpoonInstall:andUse("PushToTalk", {start = true, config = { app_switcher = { ['zoom.us'] = 'push-to-talk' }}})`
+--- and separate keybinding to toggle states with lambda function `function() spoon.PushToTalk.toggleStates({'push-to-talk', 'release-to-talk'}) end`
