Good idea. I would never have picked you as a mouse-jockey
You say that like it's a bad thing.
Okay, i started to write up a big excuse for why i use the mouse... but i've reconsidered. Instead, I will defend my honor by saying i've been using a little windows application called "wonderful icon" since the mid-nineties to enforce my own personal keyboard shortcuts upon every version of windows since 98 first edition. I'm just too lazy to learn many more.
I'd say i'm probably 30%/70% keyboard to mouse for the OS and universal shortcuts... but only like 5%/95% when it comes to program specific shortcuts.
For instance, how about a button on the channels individual button bar that toggled between "unread only" and "show all".
Upon further consideration i guess this would have to be a 3-way toggle as you also have "show new". I never use that, can you tell
