To see an action context view, click the large task selector button in the middle of Trog Bar, hover over Categories until the list pops out, find the action contexts (grouped at the end), then click the action context you want. A list of recent Categories also appears at the bottom, before the category list pops out.
You can also click any hyperlinked category when looking at it in Trog Bar.
Outlook’s task list shows you all tasks for all categories, grouped by category, including action contexts at the end. Right click any category group header and select Collapse All to see all the headers. Click + next to any header to expand the action context and see its tasks.
