If you're using Google calendar, you don't have to enter the detailed view just to add the basic information on a new entry you're creating. Instead, you can just type it in with one line. Say I wanted to change the time to reflect 12 to 3 p.m. instead of the time I clicked (8 a.m.). Instead of clicking on the edit event details link, I just type in the time along with the event description.
He goes on to say that you can not only edit the time, but location as well - nothing groundbreaking here, but it does save you a few clicks.
