What hotkey-driven and fast-paced workflows are you referring to? I used to be an Office user, now G Docs, and I hardly miss anything. Hotkeys do exist, and more complex stuff can be automated quite well with AppsScript.

Maybe I'm not enough of a power user, but these things often sound to me like the 0.1% productivity boosts that are nice to have, but often hardly relevant in the grand scheme of things.
