Talk:Accessibility guide for developers

Notes from Dodoïste
Hi there, good work on summarizing things for developers. A developers knows best what a fellow needs to works efficiently, so I'll leave the summarizing to you.

There is advice I would like to add about keyboard navigation. I'll write the full explanation here, and let you shorten it as needed. Cheers, Dodoïste (talk) 23:59, 31 July 2012 (UTC)

Keyboard navigation
Ensure that every interaction can be used by both the keyboard and the mouse. This is especially relevant for JavaScript and AJAX events. To test keyboard navigation, use the TAB key to access the interaction, and ENTER to use it.

Mouse event handlers should be accompanied by redundant keyboard event handlers. Only "Onclick" is universal.

TABINDEX should not be used, as it is difficult to use correctly and is annoying to update. The tabulation order should be natural, following the order in the HTML. The search box might be an exception where we want a TABINDEX set to 1.

Note: This issue is found in the Vector skin left navigation menu. TABINDEX is not used correctly: interaction menus come first, and the links they contain are a the bottom of the page.

Screenreader notes
I linked to 3 youtube videos at w:Wikipedia talk:Manual of Style/Accessibility, that you might find useful, and I hope we can find more.

The other software that seems to be recommended the most often, along with the commercial/demo of JAWS, and the Fangs demonstrator, are the open source NonVisual Desktop Access (NVDA) (windows) and Orca (assistive technology) (*nix). I've briefly tested out Fangs and Orca, and recommend them both.

Keydown handler for space
Why should space (keyCode 32) handled for keyboard navigation? Normally the space makes a scroll down. --Fomafix (talk) 15:39, 29 June 2014 (UTC)
 * I think that is just Mac OS X actually. But if you look around a bit you can find multiple sources with this advise: To list a few    . TheDJ (talk) 18:03, 29 June 2014 (UTC)
 * It's specific to forms - the spacebar is used for toggling things (like checking a checkbox or activating a button) if you tab to them. You can try it when tabbing into the checkboxes in the editing interface; it should be consistent across browsers. -— Isarra ༆ 05:20, 30 June 2014 (UTC)
 * I always use spacebar for that on MediaWiki with Firefox and I've never had any issue. --Nemo 14:30, 1 July 2014 (UTC)
