I'd like to have a workflow that uses a compound (two-stroke) shortcut.
Example: press Option-Ctrl-A to silently activate the start of my workflow. The next keypress will then trigger an action depending on what it is. The exact usecase is for switching apps where I'd rather not have a separate hotkeys for each app, but instead a single one to activate the mode and then type "T" for Terminal, "V" for Vim, etc. etc.. If no valid second stroke was entered the flow could simply not activate.
I know I could do this with the typical command {query} syntax, but Is it possible to do this as a true hotkey shortcut, without popping up the Alfred window, taking text input, and then hitting enter to submit it?
