Here we have the Assign Categories dialog. It comes pre-installed with Entourage and will be our first stop towards building a mouse-free workflow.
Here’s how it works:
1. Start by creating a sample task. Load Entourage and hit ⌘-5 to open Task View. Type ⌘-N and a new “Untitled” task window appears.
2. Hit ⌘-; and the Assign Categories window pops up.
3. Start typing the name of the category you want and watch as this line-item is instantly highlighted for you in the Assign Categories window.
4. To select (or deselect) the item, hit the Space Bar.
5. You can then start typing the name of the next category you want or hit Enter to confirm your choice.
