In the second mode, click-type is +determined by the direction in which the user moves the mouse after the dwell time has elapsed. There is only a determined amount +of time to move the mouse to indicate the click type; after that time has elapsed the pointer movement does not trigger a click until after +the dwell time of the next pointer stop.

The type of click may optionally be set beforehand (Alt-B) with the ClickType floating window (Alt-W) or Dwell Click panel applet. The click-type can be single, double, drag or right. Lastly, mouse direction movement can also specify the click type to be issued (Alt-U) - eg, moving the mouse left will result in a single click by default, or you may specify which direction equals what type of click. +</para> +<para> +The two available operating modes may be summarized as follows: +</para> +<para> +<emphasis>Choose type of click beforehand (Alt-B)</emphasis> - the click type selected in the ClickType floating window (Alt-W) or the Dwell Click applet is automatically issued after the given delay. +</para> +<para> +<emphasis>Choose type of click with mouse movement (Alt-U)</emphasis> - at the end of the given delay, the shape of the pointer turns into a cross. If the user moves the pointer while it is showing the cross, the direction of the movement specifies what click type is issued and triggers the click. If the user does not move the pointer while it is showing a cross (which lasts only a short time) it turns back to its arrow shape and no automatic click is performed for that move-stop cycle. +</para> +</section> + +<section> +<title>Pointer Capture</title> +<para> +The mouse pointer can be locked into an area of the screen so the pointing device is free for other tasks. +</para> +<para> +The <application>Pointer Capture</application> panel applet creates such an area on the panel, into which the user can lock the pointer until released in a determined way. +</para> + +<para> +The <application>Pointer Capture</application> panel applet can be enabled by right-clicking the GNOME Desktop menu bar / system panel, selecting <guilabel>Add to Panel</guilabel>, choosing <application>Pointer Capture</application> and clicking the <guilabel>Add</guilabel> button. +</para> +<para> +Preferences may be set by choosing <guilabel>Preferences</guilabel> in the context menu of the <application>Pointer Capture</application> applet: +</para> +<para> +In the <guilabel>Capture Pointer</guilabel> section, the user can specify under what circumstances the pointer gets captured when it moves into the capture area.
