Don't know if this was mentioned, but I just found how to use the SEEK feature in the standard Media Player using the arrow keys.

RIGHT ARROW - 5 sec jump forward
LEFT ARROW - 5 sec jump reverse
UP ARROW - 10 sec jump forward
DOWN ARROW - 10 sec jump reverse

So there is FWD, REV, FFWD and FREV with those keys

Oh and PAUSE [||] with the SPACEBAR

Wait !wAIT! There is more!

CTRL -L opens media controls and again to remove (or full screen)

Cheers
