On a recent new install of OSX, I noticed that when surfing the Web in Safari or Firefox that when I hit the tab key, every button in the toolbar, on the page and every text box was highlighted. This was different than what I was used to seeing, which was only the text fields such as the Location bar (address box) and text fields being highlighted. It took me a while to figure out why all the active controls were being highlighted. A visit to OSX System Preferences>Keyboard and Mouse Preferences>Keyboard Shortcuts got me on the right track. As seen in the graphic above, you have two options. The first option titled Text boxes and lists only seems like the obvious choice to select if you only want to tab to text input fields. However, my results were just the opposite, every time I hit tab the buttons in the browser bar and on the page were highlighted. By selecting the second option, All controls, I got what I wanted which was just tabbing to text fields. Perhaps I have a ghost in the system, but if you’re having the same problem, you may want to take a look at this workaround.
