Sets the logical button mapping for this device, see XSetPointerMapping(3). The string must
|
||
be a space-separated list of button mappings in the order of the logical buttons on the
|
||
device, starting with button 1. The default mapping is "1 2 3 ... 32". A mapping of 0 deac‐
|
||
tivates the button. Multiple buttons can have the same mapping. Invalid mapping strings are
|
||
discarded and the default mapping is used for all buttons. Buttons not specified in the
|
||
user's mapping use the default mapping. See section BUTTON MAPPING for more details.
