Instantly Invoke Old Pages With Google Cache Syntax

Want to look at an old version of a page? Want to know the last time Google crawled a page? You can invoke a cache of a page in Google's database by using the cache syntax. Try this query:
cache:www.yahoo.com/
And you'll get the cached version of Yahoo's home page that's in Google's index and a note about the last time the page was indexed. (Don't forget the trailing slash at the end. This trick doesn't seem to work well without a trailing slash or file name at the end.) Kind of interesting. Thanks GP!
