General browser semantic behavior when the spacebar is pressed is to have the
page scroll one page.

Attachment: Patched htmlBindings xml file to work around the missing XULCommandDispatcher in JS global context

Comment 3

[Remi Cohen-Scali]

The bug seems to occurs on all platforms and be due to the lack of a javascript
global context for XUL document. 
The bindings are done in htmlBindngs.xml (content/xbl/builtin/). The handler for
space key is a script using the commandDispatcher property of document.
The init method of the xul object initialize the property commandDispatcher with
a global XULCommandDispatcher object (from the global object of the JS context).
When using the embed widget (gtk or others) the global object is missing the
XULCommandDispatcher (and of course other objects of XUL context). Perhaps
because the container is not an XUL object ? I'll search in that direction...

Note: Shift+Space should scroll upwards (it works this way in Windows and Mac).

Pressing spacebar in mfcembed now scrolls the page.
(Note that you have to explicitly set focus to the window by clicking inside of 
the browser's client area with the mouse before the spacebar will scroll)

This is what happens inside of mozilla as well. There are other focus 
related bugs which will be addressing this issue.

Leaving this bug open so that we can continue to track the focus related issue.

Does 'Shift + Spacebar' work? (Note that this doesn't work in Mozilla.)

'Shift + Spacebar' does not work in mfcembed either.

When mozilla supports it, it should show up mfcembed as well...Thanks

scrolls once with each spacebar.
