No. And you don’t seem to ‘get it’ that this is not an accessibility issue but a usability issue.
Then why does Safari/Mac and Firefox/Mac act exactly like Opera does on all platforms: use Tab only for navigation between form controls?
Could it be that this universally required, holy method of keyboard navigation only applies to certain platforms?
They don’t. They can use Tab to navigate between form controls, A/Q to navigate between links, S/W to navigate between headings, or D/E to navigate between any elements. They can also use Shift+arrow for spatial navigation, which blows Tab navigation right out of the water. If their disability makes it difficult or impossible to use modifier keys (e.g., if they can only use one hand) they will have to change the settings to use four other keys for this, that’s true. But they’re still way better off than if they were using IE, Firefox, Safari, etc., which do not offer spatial navigation at all.
Except Safari/Mac, Safari/Win and Firefox/Mac. It’s been some time since I tested in Camino/Mac, but if I recall correctly it didn’t offer Tab navigation to links by default. I’m sorry to have to crush your illusion that Opera is alone on it’s crusade against keyboard users.
That’s really odd, because I use Opera as my main browser and I navigate almost exclusively via the keyboard. How can I do that if it’s inaccessible?
Different from IE/Firefox is not the same as broken. Try to understand that.
For you, and many others, but not for everyone. Restricting Tab to form controls is actually an improvement, whether you admit it or not. It allows me, as a constant keyboard user, to jump straight into the first form on a page without having to: (a) press Tab twenty times to bypass the navigation and all links that precede the form; or (b) move my hand to the mouse and click on the first control in the form.
Only if you leave out Mac browsers, including the precious Firefox (at least V1.5, which is what I tested in).
You can spread this FUD as much as you like, but links are accessible in Opera via the keyboard. It is to do with usability, arguably, not accessibility. And if you want to use the Tab key, Opera lets you do it. Most of its user base don’t, which is why the default settings are what they are.
Please accept that others may have different preferences from yours.
