OK, one more: end user manual

  • Having solved the rest of my problems, here's another one that popped up:

    Not all of the icons are self-explanatory. I've had my customer (who isn't the computer illiterate as the end users mostly are) complain about being unable to do a few things until I told him where to click. Then he asked whether there's some sort of end-user manual with explanations of all the buttons.

    I've searched the site and found only programmers' reference material, but no end user stuff. So... is there such a thing?
