Hey Zac,

I really like Diffractor!

Please add keyboard shortcuts to skip forward and backward during video playback (e.g., by 5 or 10 seconds).

This would greatly improve usability for users navigating through videos.

For example, in VLC Media Player, pressing Ctrl + Right Arrow skips forward 10 seconds, and Ctrl + Left Arrow skips backward 10 seconds.

Similar functionality in Diffractor would be very helpful.

Thanks!
