2.3. Traversal

Traversal keys move focus within the window and optionally invoke an action on a control. Traversal keys differ from accelerators and window system keys (which are discussed later in this chapter) in the following manner: It is up to the focus control to decide whether to perform the traversal operation or process the key. In the case of accelerators and window system keys, they are consumed before the control has a chance to see them. When a traversal operation is performed, the traversal key is consumed to stop further processing by the focus control.

There are two kinds of traversal: mnemonic and tab.
