Please add a way to pause (speed=0) as well as resume last speed.

While it's not about speed, having keys for +/- volume would be a really handy for complete video control from the keyboard.

Thanks for a really useful plugin!

When I right click the extension icon in my toolbar, and click settings, I am brought to a settings page. Here I am able to adjust the hotkeys for commands like Advance and Rewind. However, I am unable to adjust the Advance Time or Rewind Time increments. The default is 10. When I try to erase this value or replace it with a different one, nothing happens.
