One of the most sought after requirements for the Viigo was the ability to actually have the keyboard shortcuts in place for common functions.

We are still awaiting Viigo to announce a way of getting around the bug, of using the spacebar to page down in articles. It has been said that they have added two new shortcuts.

Now you can forward an article via email by just simply hitting the f key, and to send it to yourself just hit the s key. Both of these shortcuts have been tried and tested on Viigo version 3.1.330 the f key shortcut worked but the s key shortcut didn’t. Strangely hitting the d key forwarded the article also.
