|

|
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.
