If flyby highlighting is enabled, a tab’s text will be underlined and use a different text color when the mouse cursor is above a tab.

Flyby highlighting is optional (see SFTTABS_CONTROL) and can be defined using the SftTabs/DLL Wizard.

If the defined tab control style supports and uses themes, flyby highlighting should be enabled. Instead of underlining the text, the defined theme's representation method is used when the mouse cursor is above a tab.

Windows Mobile Edition: Flyby highlighting is not available, because Windows Mobile operating systems do not have a cursor/mouse position. For source code compatibility, API functions for flyby highlighting are available, but are ignored when used.
