I first came across quick reference cards in the early 1980s I think the first one may have been a Digital Equipment Corporation MACRO-11 quick reference card. I found that they suited me in that I could generally remember what each command did, but I could often not remember the arguments or I might forget about the existence of particular commands.
Later I came across the GNU emacs editor (which is now my editor of choice if I can't use Emacs, I use ed).
Nowerdays I often put together a reference card when I am getting to grips with a new technology (e.g. the Perl XML::LibXML modules).
The refcards.com web site collects my own cards and those of others. I have quite a few cards in various stages of development, that I will be adding over the coming months. I will also be adding links to refcards and cheatsheets hosted on other sites as I come across them.
I have various vague plans for refcards.com:
I will get round to these in time.
