                display 
              
                A
                display. 
              
                :result-type 
              
                The type of sequence to return.
             
              Returns or (with setf) changes the mapping of button
              numbers for the display pointer. The :result-type
              is not used when changing the mapping. If element i of
              the mapping sequence is j, then the events from pointer
              button j are reported by the server as events for button
              i+1. (Note that pointer buttons are numbered beginning
              with one, while the mapping sequence itself is indexed normally
              from zero.) If element i of the mapping sequence is zero,
              then button i+1 is disabled and can no longer generate
              input events. No two elements of the mapping can have the same
              non-zero value. 
             
              The length of the mapping sequence indicates the actual number
              of buttons on the device. When changing the mapping, the new
              mapping must have this same length.

                card8.
