You may not have heard about Quick Events in OSX Lion but you should know about them because they’ll save you lots of time.
In Calendar, click the “+” symbol on the top left of the window and a little pop-up will open.
You can create events here using plain English. For example, I just created an appointment for me to go and see a client on Friday morning at 10 by typing “Go and see Fred Flintstone at 10AM”.
Press Enter and it’s done. Appointment created.
If you want to create an event that’s an hour long, don’t give an end time, if it’s longer than an hour then type “see Fred on Tuesday from 1pm to 4pm”, or if you want to create a multi day even give the start and end dates.
Clever huh?
