Help and implementation of "Skip forward/back (enter time)" confusing

[prl]

There are four functions in InfoBarGenerics.py that implement the actions for long LEFT/RIGHT/REW/FF as either bringing up a Seekbar or as an entry box to enter the time. There is only help available for long LEFT/RIGHT, and it only mentions entering a time, not the seekpar. It is further complicated by the poorly documented MENU>Setup>TV>Recording settings>Seekbar activation which appears to only change the activation of the seekbar, but it in fact swaps the seekbar and skip time entry functions between the long-press (LEFT/RIGHT) and (REW/FF) keypress pairs.

In the Seekbar, only LEFT/RIGHT can be used for positioning, and their skip sizes are set by MENU>Setup>TV>Recording settings>Seekbar sensibility. This isn't bad in itself, but again is poorly documented and not helped by the curious name choice (the description text is better).

The original enhancement request (enhancement 263) that contained this request also suggested that all the skip buttons 1/3/4/6/7/9 and PREV/NEXT for bookmark jumps should be available here, but I'm not convinced, since they are already directly available without invoking the seekbar.
