Hi Ken,
the key abstraction layer is trying to getting things as conform as possible
for all browsers. However, when it comes to the modifiers and key events being
fired there might be issues concerning the event order and the infos you get
across different browsers.
One last idea I have in mind: what about the "keyup" event? Otherwise I would
tend to write a small portion of browser-specific code as first solution. It
might be also a valid candidate for a bug report.
Regards,
Alex

Subject: [qooxdoo-devel] keyInput event on alt-/ only in FireFox?
Platform: Running qooxdoo 3.0 on Windows 8 (server and browsers)
I am trying to support Emacs-like key chords in my custom math editor. For
example, I translate alt-/ to an inline division symbol. Editing takes place
in a a qx.ui.embed.Html widget where I have MathJax render TeX generated by my
editor.
The alt-/ keychord works great on FireFox where I get a keyInput event with "/"
as the keyIdentifier and 4 (alt) as the modifiers, but on Chrome 28.0.1500.95
m, Safari 5.1.7, and IE 10.09 no keyInput event is received.
What I do get is a keypress event only on the alt key being pressed, then a
keydown event where the keyIdentifier is 'Undefined'. The keyDown event does
offer a keyCode of 191 with 4 as the modifiers so I have a workaround, but then
I have to write browser-specific code since the keyCodes are not standardized.
Is this something I can hack into qooxdoo myself, or are the browsers the
problem?
Cheers, ken
ps. Nice work on qooxoo 3.0 minimizing the dom!
