You should really try acutally using VLC for a while, then you'd know that it does, in fact, do exactly that. Try shift, alt or ctrl plus an arrow key for a small, medium or large jump, respectively. The fact is that VLC can do so much more useful stuff than any other video player that you're crazy not to use it. One obvious feature that you can't live without is that you can modify the syncing between the audio and video on the fly with the j/k keys. So if your video is out of sync, you can easily fix that. Another thing is that it can crop the video on the fly, so if you have a 16:9 video on a 16:10 screen, you can just crop it to the right aspect ratio so you don't get any black bars. And it can do so, so much more. Really, it's insanity to use anything else.
