Patch to use Skip keys (Next + Previous) - vdr

20 Feb 2006

Hallo
Since a long time I wondered when the very common skip keys are 
available in VDR.
I believe these keys are available but unused on most remote controls.
The attached patch adds to new keys kNext and kPrevious to keys.h and 
keys.c.
The patch modifies vdr.c and menu.c to switch channel up/down whith the 
new keys.
I also modified the mp3 and dvd plugins to use the new keys. I can 
provide patches therefor
if the patch will be intergrated in VDR.
As logical mp3 jumps between tracks.
When playing a DVD Next and Previous have the same meaning like 4 and 6 
and jump
between DVD chapters. That is the common behaviour of stand-alone DVD 
players.
Very smart when replaying music DVDs because the different songs  are 
DVD chapters.
I can also imagine to use Prev/Next to navigate between cutting marks in 
a recording. (not yet implemented)
If you find the new keys useful please contact the list to convince 
Klaus to integrate the patch.
Regards Peter
