High Quality Content by WIKIPEDIA articles! Xmouse is a system of mouse control used instead of the standard system of selection on computers (most notably Windows and X11, where it is an option). Where normal mouse control uses single-click for selection and double-click to open/edit/etc, the xmouse system automatically selects objects after hovering the mouse over the object for a certain period of time (often one second). The context function, previously activated by double-clicking is activated by single-clicking. Double-clicking is made redundant by this system and is ignored. Operation of menus, text selection and other features remain unchanged.
