-- I want "type = mapM_ (press . KeyChord [] . key)" to be "atomic" i.e. no delay between each step. I want "press (KeyChord [Command] RKey) >> type text" to be "laggy" i.e. some delay between each step. If I "instrument" some "Workflow", by interleaving "Wait 25" between each step i.e. each "Free _", I can't distinguish between groups of steps. Thus, I should manually insert "Wait 25" between any steps that need some lag, or "automate it locally" in helper functions, but not "automate it globally" by interleaving.
