Download of wasd 1.0 for Mac was on the developer's website when we last checked. We cannot confirm if there is a free download of this app available. The actual developer of this free Mac application is Stubbit. We recommend checking the downloaded files with any free antivirus. The application lies within Internet & Network Tools, more precisely Browsers.
From the developer:
wasd is a simple Safari extension that lets you adjust the Vim keybindings.
You may want to check out more Mac applications, such as BATTLE BEARS -1 Mac, Angry Bots or MIRRORMOON, which might be similar to wasd.
