Give it two examples, and Google's spreadsheet can make a list of almost anything.
reported that if you make a spreadsheet in Google Drive (Google Docs, formerly), enter and highlight the names of two beers, and pull down on the corner of the spreadsheet cell while holding Option or Control, the app will automatically fill the following cells with the names of other beers. The information is pulled, seemingly, from nowhere.
It doesn't just work for beer, car brands, colors, states, or websites, as reported, but just about any category you can think of. The feature was an outgrowth of a discontinued Google Labs project called Google Sets, so it's no longer pulling real time information.
