I like this new AIR application for searching and browsing keyboard shortcuts.
This application contains a database of all of the keyboard shortcuts for all of the applications in Creative Suite 4.
To see all of the shortcuts, be sure to click All Categories. The default Essentials view just shows a small subset.
For After Effects, the information appears to be identical to that in the “Keyboard shortcuts” section of After Effects Help. (I’d recognize my own writing anywhere.)
I like the search features in the AIR application, and I also like the fact that I have the shortcuts for all of the applications that I use all in one place.
If you want to search for keyboard shortcuts in After Effects CS4 Help, you can do that, too.
For information on editing keyboard shortcuts, see the top of this page.
