Where do you keep your bag of tricks?

[JohnGage]

Where do you keep your list of tips and tricks that you don't want to have to remember or research every time you need one?  I have a lengthly text document that I store complex Excel formulas, locations of log files I rarely need, TAMdbfr commands, registry hacks, etc... Since it's in a text file I use Ctrl+F to search for a word I think I used when the tip was originally entered but that doesn't always work. 

I'm considering moving the content to Evernote and using tags to identify the program or hardware the tip pertains to.  Thought I would ask what everyone else does in case there's a better option I hadn't thought of.

I was just thinking of Evernote - I was just introduced to it and this sounds like a good use for it. You could snip web content to it, too (like AU posts), without having to copy/paste or retype them.

We use Track-It! as our helpdesk software and it has a "Solutions" section where all of us post ...well, solutions and stuff

I jot it all down on the inside wall of my cranium... Oi it hurts sometimes!!!!

I ask someone smart, then find that I don't like the answer, so I google it.

KB, doc central, google (for those really odd things that aren't TAM like outlook errors), we also have a few other internal support resources that I can't share the details of...
Onenote for anything thats generally not covered by the above, or hard copies stuck to the cubical wall (inbetween extensions, certificates and pictures of cars I will likely never own).

Once in a while if I'm really stumped, I may ask another human being for help. Depending on how strange the issue is, that may give mixed results.
