The ubiquitous internet gadfly, and productivity guru, Merlin Mann recently launched yet another online venture: The Merlin Show. The first five episodes have nothing to do with Apple (though they are interesting), however, the latest episode covers a TUAW favorite, Quicksilver.
Merlin shows us how ,armed only with Quicksilver and the comma key, you can save a few moments queueing up tasks you want done on multiple files at the same time. Watch the short video and learn a thing. You'll thank me later.
