I use a global journal. Just a wirebound notebook to jot notes. I write down user story or bug fix ids if I'm working on those, if not I'll try and make some sort of title to what I'm doing. I find it is handy when a problem comes up, I can say I fixed the issue, here's what I did and why. Or if it's new development and I'm asked why didn't I do blah, I can show that I did and here are the results and why I chose alt-blah. Mostly it's a memory tool.
