Someone showed it to me and it changed my life...or at least seemed like a pretty cool tip. On Cisco devices, you can filter the "show run" output by entering a forward slash (/) at the more prompt and typing in the section you want to move to.
Router# show run

--More-- <---- enter the forward slash here followed by a word (such as interface) that you want to jump to.
This is essentially like doing the "show run | begin" syntax, but you can do it on the fly. Okay, maybe not life changing, but sure is handy on those massive config files.
