1 With TPB it is possible to bind programs to the ThinkPad, Mail, Home and
2 Search buttons. TPB can also run a callback program on each state change with
3 the changed state and the new state as options. So it is possible to trigger
4 several actions on different events.
6 TPB has an on-screen display (OSD) to show volume, mute, brightness and some
7 other information. Furthermore TPB supports a software mixer, as some models
8 of the R series ThinkPads have no hardware mixer to change the volume.
