- The X server for MkLinux DR2.1 uses the following unused keycodes to

-
- 0x7e This indicates that the next two keycodes should be interpreted
- as mouse information. The first following byte's high bit
- represents the state of the left button. The lower seven bits
- represent the x-axis acceleration. The lower seven bits of the
- second byte represent y-axis acceleration.
-
- 0x3f The x server interprets this keycode as a middle button

-
- 0xbf The x server interprets this keycode as a middle button
- depress.
-
- 0x40 The x server interprets this keycode as a right button
- release.

- 0xc0 The x server interprets this keycode as a right button
- depress.
-
- NOTES: There should be a better way of handling mice in the X server.
- The MOUSE_ESCAPE code (0x7e) should be followed by three bytes instead
- of two. The three mouse buttons should then, in the X server, be read
