Ages ago, I used an app that allowed me to edit text from one app in another app. My memory is vague, but I think I remember writing in Writeroom for notes that were otherwise created and managed in Notational Velocity.
I’d like to be able to do this today… be in DT or TBX or Mail and with a keystroke, be instantly transported to a better* interface for composing, then with another keystroke, be back in the original app ready to hit send or save.
Anyone know of anything that does this?
* plain-text, full screen, nice font, typewriter mode
