Re: accessible drop-down menus

Hi David,

Thanks for sharing the video.  It was good to hear your voice again. It’s been some time.  An operating system setting is preventing you from accessing those controls with the keyboard in firefox.  If you were a Mac OS X user who relied on keyboard only navigation, one of the first OS customizations you would make would be to change your Keyboard settings to move focus to All controls rather than just Text boxes and lists only.  To do so, open up your System Preferences, then open up Keyboard, then open up the Shortcuts tab (because that is the most logical place to put such a setting <— sarcasm).  At the bottom of the tab you will see a set of radio buttons with the label Full Keyboard Access.  You will want to change that from Text boxes and lists only to All controls.  You can also toggle this setting at any time using the Control + F7 key combination.  Once you toggle this setting, you should be able to use Brian’s aria menu without a problem in Firefox with the keyboard.

Best,

Mark

It is similar (but not the same) as the Canadian Gov Web Experience Toolkit Working Examples Menu (https://wet-boew.github.io/v4.0-ci/demos/menu/menu-en.html <https://wet-boew.github.io/v4.0-ci/demos/menu/menu-en.html>)

> It appears your menu follows the DHTML guidelines which suggest that only the first (or just one) of the main navigation items should be accessible with the tab key, with the others accessed via the arrow keys (i.e. more follows the standard paradigm used with computer applications such as Window Explorer). However, from my testing with keyboard users (with and without a screen reader) I find that a significant proportion expect to be able to tab to all the main navigation items in a web page, and become a little disorientated when this doesn’t happen. And in some cases, either they don’t think to use the arrow keys or don’t know they can be used for this purpose.

Can anyone suggest examples that are both intuitive to use with the keyboard and accessible with a screen reader.
