I recently found out that when viewing a man page you (via "man [command]") you can search it by using forward-slash. ie, / beewee would find the first occurrence of "beewee" and by hitting "n" it's like "Find Again" and it finds the next one.
I also found out about hitting "?" to see all the cool options that are possible while viewing a man page.
[Editor's note: I had no idea ... and of course (and this time I swear I checked!) there's no mention of these features in "man man".]
