Default tab order in the EPM Workspace UI flows from left to right, top to bottom. The component order: toolbar, search control, view pane, content area, content area (bottom) tab bar. The tab order loops in both directions so that tabbing from the last item focuses the first item, and reverse-tabbing from the first item focuses the last item. The following elements are not included in the tab order:
Navigate menu
Main menu bar (use shortcut keys to access menu items)
The “Welcome <username>” message and the accompanying logoff text link (use logoff or exit icon in toolbar or items from File menu instead)
