So I enrolled for the free Keynote workshop at the Apple store.
Keynote is Apple's presentation software, like PowerPoint and all the others.
It started at 3, so I met up with trombone-buddy Bruce beforehand and we ate lunch together. Then to the Apple store.
There were just three of us, plus the trainer. He took us in an hour through the construction of a Keynote presentation.
The workshops are nominally one hour long, but he had a bit of extra time, so we had plenty of time to ask questions. I asked about projection settings, so he walked us through that.
In all I was very impressed.
So I've enrolled for two more !
