Soloing an instrument

I apologize ahead of time if this solution already exists, but did a Handbook search and didn't see anything. Is the only way to solo an instrument to go into the mixer and hit the solo button? It would be great if you could point your cursor to a staff, right click and the drop down menu had a solo/mute option. I realize right-click does allow to you do some things, but it could be much more robust.
Thanks
