In Myth, the 'P' is mapped to PAUSE by default.  The PAUSE action toggles
between Play and Pause.  The is also a PLAY action (I have it mapped to
Ctrl+P), which always goes into the Play mode.  If you are talking about
FFWD/RWND, then hitting Ctrl+P may solve that problem for you.

If you are talking about "timestretch", though, then that will not help.
Hitting PLAY (Ctrl+P) with timestretch enabled does not change back to a
1.0x play speed.  For that there is a separate "TOGGLESTRETCH" action.  On
my system that is bound to 'A'.   There is also the "ADJUSTSTRETCH" action,
which can also be used to toggle timestretch on/off, while allowing the
arrow keys to adjust the playback speed.

You can tweak what keys perform what action in Setup->Edit Keys->TV
Playback.

In Setup->Video->Playback Groups you can adjust how far Myth jumps when you
hit your Skip or Jump keys.  For example, I have my 'default' configuration
set to:

Skip ahead (seconds): 30
Skip back (seconds): 7
Jump amount (minutes): 3

You could change "Skip back" to be 30 seconds.  That will not toggle
subtitles, but I assume you have that assigned to another key?

In summary, you may be able to get most of the way to your goal without any
code changes, but with some configuration.
