 2x<B1>             print coordinates to clipboard using `clipboardformat`
                    (see keys '3', '4')
 <B2>               annotate the graph using `mouseformat` (see keys '1', '2')
                    or draw labels if `set mouse labels is on`
 <Ctrl-B2>          remove label close to pointer if `set mouse labels` is on
 <B3>               mark zoom region (only for 2d-plots and maps).
 <B1-Motion>        change view (rotation). Use <ctrl> to rotate the axes only.
 <B2-Motion>        change view (scaling). Use <ctrl> to scale the axes only.
 <Shift-B2-Motion>  vertical motion -- change xyplane
