To answer you question (plus a bit more than you asked for, since you
seem to have a little confusion on what's available), you have 6
different ways to move through a program besides normal 1X playback.

1) You can jump, which (I believe) is in increments of minute with 10
being default, and I don't believe there are separate settings for
forward and back. I don't recall which key does this.

2) You can seek, which is in increments of second...don't recall the
default, and this is configurable for forward and back (I use 30
seconds forward, 10 seconds. The keys for this are SEEKFFWD and
SEEKRWND.

3) Using those same keys, you can actually seek an arbitrary number of
minutes forward or backward. If you want to jump ahead 23 minutes, you
hi the keys 2, then 3, then SEEKFFWD. To jump back 1 hour 24 minutes,
you'd hit 124 then SEEKRWND.

4) You can use the FFWDSTICKY and RWNDSTICKY keys to seek through at
high speed. This is similar to how a VCR/DVD player allows you to
fastforward and rewind while still watching the video. You get no
sound when doing this. You can configure the playback speeds
increments (default is something like 2X, 5X, 20X, etc), but there is
no GUI for it so you have to modify them in the database directly. I
did release a patch for 0.21 that allows you to configure the
increments in the GUI, as well as give you some better control of some
of the settings, but nobody took an interest in adding it. I'm not
sure how well it applies against 0.22 now. The patch is in ticket
4492.

5) You can use the stretch feature to adjust the playback rate from
between 0.5X (I think) and 2.0X. This is user adjustable at playback
time. You can use the ADJUSTSTRETCH key to bring up a speed adjustment
control during playback, or you can use TOGGLESTRETCH, STRETCHINC, and
STRETCHDEC keys. One advantage of this over the other methods is that
you continue to hear audio.

6) You can also playback in slow motion using the SPEEDDEC key.
