I'm basically looking to create a one-handed app launcher that's as simple and painless as possible. The idea is that you can just double-tap a modifier key (e.g., Command) and then type a single character to launch an application. For example; Command+Command + c would open Calendar.app. The trick is not requiring the user to hit enter, as that's just an extra step. Thinking this should be easy but I'm not sure I see a way to get around hitting enter to move to there next step.
Current workflow looks like this;
1) [hotkey] Double-tap Command -- this opens alfred and links to a script filter
2) [script filter] set to argument required, user types 'c', script processes and filters to an item (e.g., Calendarl)
3) ???
4) [launch app] Launch Calendar.app
5) Profit
Any thoughts?
