If you like strings, you may want to look into grep. That command finds all occurrences of a regular expression in a file, which makes finding a particular description quite a bit easier. For a simple example, grep "Starspawns are ancient" <file> gives the one matching description.

If you are into screenshots, I'd suggest using the scrot program. Besides having the worst name ever, this program takes screenshots through a command line interface, so you can easily write a 'take screenshot after 10 seconds and upload it to FTP and send URL somewhere' one-shot script.

Neither solution is *quite* what you ask for, of course, but that should still be more convenient than typing descriptions by hand.
