form tabbing skips <button>

Question

is there a reason Firefox and Safari (on my Mac) are skipping over the element when I tab between fields in this form?

<form> <input type="text" name="tags" id="tags" tabindex=1/> <button id="launch" tabindex=2>do it!</button> <textarea name="comment" id="comment" tabindex=3></textarea> </form>

I shouldn't have to put tabindex in, but even with it it skips the button. I have seen documentation that button elements should accept tabindex.

thanks

It worked for me in Chrome on Linux, so it might not be a problem with your HTML.

One guess: Mac OS by default does not make buttons focusable with Tab-- only text boxes and lists. Maybe Firefox and Safari are merely respecting this setting. You can change it in the System Preferences.
