Florian Ebeling has released Keys on the Mac App Store. It’s being offered for US$19.99 instead of the regular price of $29.99 through June 2 as an introductory special.
Keys is an application for learning to type with 10 fingers. It offers 24 lessons that familiarize learners with more and more areas of the keyboard.
During the training help indicators show the next character to type on the keyboard, and which finger to move there. This version of Keys only supports the US keyboard layout, but additional layouts are planned (especially a German one) and will be made available as free updates.
