Google Calendar – How to Add a Task via Quick Add Feature

You can't select which calendar in Quick Add. However if you add event by clicking on your calender grid, you can bring up a dialog which allows you to select your calendar. That's pretty quick to me too. E.g. I can say "@7am dentist appt", then select a calendar, then submit, this doesn't go through the full calendar configuration screen.

There are 2 ways to quick-add your event:

1. Open the Event "pane", clicking on your calendar, or by pressing Shift + c

2. Open the quick-add box, by pressing q

There is no support for choosing default calendar for both #1 and #2. But with #1, if you uncheck visibility of other calendars, then you event will go to the first visible calendar, which is sort of workaround to pick default calendar.
