You can change the mapping of buttons on the pointer by using options in the X*pointerkeys file. The
following table lists the X*pointerkeys functions that control button mapping and their default values.
Like xmodmap and xset, these functions affect only the X pointer, not any extension input devices.
Button Mapping Functions
Button Mapping Function Default Key
Set button 1 value button_1_value 1
Set button 2 value button_2_value 2
Set button 3 value button_3_value 3
Set button 4 value button_4_value 4
Set button 5 value button_5_value 5
You can change the key sequence that exits the X Window System. Also, if you use both image and
overlay planes, you can change the distance you must move the pointer before you switch planes. The
following table lists these options, the X*pointerkeys functions that control them, and their default
values:
Reset and Threshold Functions
Option Function Default Key
Exit the X Window System reset break
Add a modifier to the exit key reset_mod1 control
Add a modifier to the exit key reset_mod2 left_shift
Add a modifier to the exit key reset_mod3 no default
Set the threshold for changing
between screens
screen_change_amt 30 pixels (0 if a graphics tablet is
used)
screen_change_amt is used only if your system is configured for more than one screen.
screen_change_amt enables you to avoid switching from one screen to another if you accidentally run
the pointer off the edge of the screen. screen_change_amt establishes a "distance threshold" that the
pointer must exceed before the server switches screens. As the previous table shows, the default width of
the threshold is 30 pixels, but acceptable values range from 0 to 255.
When a graphics tablet is used as the X pointer, the screen_change_amt defines an area at the left and
right edges of the tablet surface that will be used to control screen changes. Moving the puck or stylus
into the left or right area will cause the X server to switch to the previous or next screen.
