Windows power-users are a fickle bunch, and to them the average list of "super-secret Windows tips" is about as fresh as the average Windows ME install. I found a surprising number of gems, however, in this Joel on Software discussion thread. Did you know, for example, that in Microsoft word you can type =rand() anywhere and it will be replaced with filler text (more if you put a number in the parentheses)? Or that Alt+Esc sends the active window the the background? Or that Shift+* will expand all of the subdirectories in a directory tree? Advice is also proffered in the form of registry tweaks and downloadable utilities. Post your own super ninja Windows tips in your comments.
