Since people may notice this post, I'll add that one thing I stumbled across is that you can use number keys (alone) for a little bit of site navigation.
The black bar at the top has five items--forums, classifieds, media, members, and strava. If you're happen to be viewing something in forums, hit a 2, 3, or 4 and it will create a drop down from that heading. Hitting 5 will take you direct to the TCC strava page.
If you're within classifieds, hit 1, and there'll be a drop down with some options for the various forums.
This may be old news to some folks, but I only recently noticed this. While it would be nice to navigate further like this (eg, to the items that drop down under forums), I haven't figured that out yet. (So if anyone knows...?)
Edit: after hitting a number to produce the dropdowns, down/up arrow keys move you to the various choices. Then hit return to go there.
