ShellBrowser Delphi Components Documentation
Specifies whether list items are highlighted when the mouse passes over them.
Set HotTrack to true to provide visual feedback about which item is under the mouse. When HotTrack is true, the HoverTime property controls whether pausing the mouse over an item causes it to be selected. When HotTrack is false, there is no visual feedback when the mouse passes over items and users can't select items by pausing the mouse.
