I'm running Linux Mint, and the menu for setting keyboard shortcuts that work even when Strawberry does not have focus warns against using such shortcuts with Cinnamon.

But I don't actually need my keyboard shortcuts to work when Strawberry does not have focus. Are there, or is there a way to set up, keyboard shortcuts that work only when Strawberry is the active window? Specifically, I want to go forward and backward by whole tracks, and I want to raise and lower the volume.

The keyboards on the machines in question (one of which is a laptop) do not have dedicated keys for skipping tracks, and the dedicated volume keys adjust the volume at the OS level.

Thank you!
