In Donedesk, action contexts are tags with no special starting character, like: Calls, Grocery, Bookstore. Use short names.

If an action context should be shared, use a workspace instead of a tag. Example: Errands. A shared errands list is a powerful thing! Anyone can pick up those items when they are on the road.
