Use Flat/Hierarchical Numbering — Choose whether to number all tasks sequentially regardless of hierarchy, or to use dots to create hierarchical numbers for group members (item 2.1 and 2.2 are children of item 2).
Show Overview — Turn on or off a zoomed-out view of the whole Gantt chart, with a draggable box representing the currently visible area.
View Options — Show the view options dialog, where you can set which columns are visible in the outlines and how to draw the charts. Each view has its own view options dialog.
Row Text — Choose whether the text in a multi-line item should always be visible, or should be folded down to one line when you're not editing it.
Expand All — Open all collapsed groups in the outline to show their contents.
Filter Tasks — Create a filter that makes the task outline show only tasks that meet certain criteria.
