Button Chording

Option

Function

Default Action

Turn button chording off or on

button_chording

On for devices with two buttons,

 

 

off for devices with more than

 

 

two buttons

Button chording refers to the generation of a button-press by pressing two other buttons. If you have a two-button mouse, you can generate Button 3 by pressing both buttons together. With a three-button mouse, you can generate button 4 by pressing the left and middle buttons together and button 5 by pressing the middle and right buttons together. See the button chording examples in the X*pointerkeys file.

You can also use the X*pointerkeys file to configure pointer buttons so they are latched. When this feature is enabled, a button you press stays logically down until you press it again. See the example X*pointerkeys file in /usr/lib/X11 for information on configuring this functionality.

____________________________________________________________________________________

Note: The sample X*pointerkeys file is placed in /usr/lib/X11 at install time. If you subsequently update your system, the X*pointerkeys file in /usr/lib/X11 is not overwritten, and the sample file is placed in /usr/newconfig.

Specifying a Portion of a Tablet

Option

Function

Default

Use a subset of the tablet surface

tablet_subset_width

disabled

as the X pointer device

tablet_subset_height

 

 

tablet_subset_xorigin

 

 

tablet_subset_yorigin

 

If a tablet is used as the X pointer device, it may be desirable to use only a portion of the tablet surface. A rectangular subset of the surface may be specified with these functions. The units are in millimeters from the upper left corner of the tablet surface. For example, if you want to use only an "A" size portion of a larger "B" size tablet, the following lines could be added to the X*pointerkeys file:

tablet_subset_xorigin 68 tablet_subset_yorigin 40 tablet_subset_width 296 tablet_subset_height 216
