Tabbing to a button

Ok, to start things off, I thought I'd mention the issue of tabbing. I was used to tabbing my way through the data entry websites i use everyday for my job. One of my pet peeves about using my Mac was that I couldn't just rely on the keyboard - whenever i would come to a button on a website, I needed to use my mouse to click on it. I thought this was strange as I wondered what some users with accessibility issues would do under this situation. I then found that this was actually a config option and Mac OS X just comes with tabbing to a button as disabled. You can resole this by doing the following:

Click on System Preferences-Keyboard & Mouse
Click on the 'Keyboard Shortcuts' tab
Under 'full keyboard access' choose the 'All controls' radio button.

Thats it! Now you should be able to tab through Forms and webpages with ease :)
