Is there a way that I can change my Chromebook's scrolling as OS X Lion's reverse scrolling? I both use Chromebook and MacBook Air. Reverse scrolling just makes sense.
See Use your Chromebook touchpad in the Chromebook Help.
Originally, the Macify extension for Google Chrome also included a rough implementation of Apple's Natural Scrolling, Chrome OS now includes it out-of-the-box. To enable, just go to:
chrome://settings/pointer-overlay
and select Australian scrolling.
