[Enhancement] Keyboard shortcut for adjusting volume

[tuukkao]

Having a keyboard shortcut for adjusting LMS's volume in the ui would be handy. I'm blind and using LMS with the keyboard exclusively. While the slider does work a dedicated keyboard shortcut would do the same thing a lot quicker.

Some suggestions on how this could work:

• ctrl+up/down
• Adjust in 10 % increments rounding to the closest 10 % if necessary
  • e.g. If the slider is at 14 %, round up to 20 % when increasing the volume and down 10 % when decreasing.

I would be happy to work on a PR if you think this would be useful and at least a somewhat trivial first issue.

Also, thanks for your great work! I use LMS as my almost-daily driver for listening to my music collection and I really appreciate the design choices you've made.

Hello! Thanks for your feedback.

Indeed this could be done. It should be quite easy to do , as it is only js code (have a look in media player.js, where the keydownevent is handled)
Feel free to open a PR!
