I do a lot of listening to songs I need to learn, which means I often want to rewind or fast forward a few seconds. Instinctively I want to use my arrow keys. Is there a plugin for Banshee that can help with that or some controls that I'm just not seeing? I can move the scrubber with my trackpad, but it isn't very precise. I'd rather use keystrokes.
Shift + Left: rewind song by 10 seconds. Shift + Right: fast-forward song by 10 seconds
But more sources that Banshee does not have shortcuts for those actions (...). Please try and comment if these do not work and I shall remove this answer.
1.9.4 February 23, 2011
If it worked after this update someone removed it again (and it does not show in the other changelogs :P )
This seems interesting: https://mail.gnome.org/archives/banshee-list/2012-June/msg00029.html It states Banshee does NOT have keys for FF and RW but that this person wants it (and believes he can create it). Of course he never replied that he did get it done ;)
Conclusion: Banshee does not have a working rewind of fast forward.
