You can set Tasker to trigger silent mode based on specific calendar events if you go to State -> Calendar Entry. There are a number of ways you can trigger it: 1. You can have it be silent if your calendar indicates you're busy. 2. You can create another calendar called "silent" and have it be silent for all events in that calendar. 3. You can set the location of the calendar entry to "Silent" or have it trigger for specific locations. 4. You can have it trigger for entries with the title "Meeting" or "Movies" Then, you can add an exit task that sets it back to your default settings when the event is over. A slightly more advanced/complicated approach, but closer to what I think you want, is to write a script using the Android Scripting Environment that shows a dialog where you can enter how many minutes you want silent mode to be enabled. Then have it wait until x minutes have passed and then disable silent mode. You can then set Tasker to run that script for a specific condition, such as long pressing the search button.
