Keyboard Shortcuts
This feature allows you to use a pop-up menu to change your
desktop settings without exiting your current application. You can
configure, enable or disable shortcut features when you click the
Shortcut icon in the control panel.
The ATI Popup Menu only displays the valid and safe modes
available for the attached monitor(s). Additional modes may be
accessed through the Monitors & Sound control panel or the
Control Strip.
Different ATI cards offer distinct keyboard shortcut options, so
not all shortcuts appear on every ATI card.
NOTE
Popup Menu and Hot Keys remain inactive when dialogs appear on
the screen. For example, while using the Monitors & Sound control
panel, the Popup Menu and Hot Keys are disabled.
