I would like to create a shortcut that allows me to start and stop my time tracking/Pomodoro timer software (Toggl). My normal routine is to click on the extension I have on Google Chrome...but there's also a desktop app if doing it via Chrome isn't possible.
I'm sure you'll get better ideas, but my simple approach would be to trigger Activate a specific application (Toggl.app) and then Type keystroke the default key for the app to start a timer (⌘T, I think), and then Activate last application to continue working.
