Menu: support keyboard menu invocation on safari/mac

[bill]

Apparently even on Safari V4/mac, there's no way to open a context menu (dijit's context menu or the default browser context menu) via the keyboard.

Do we want to support this?

I think we could setup an onkeypress handler to catch ctrl-space (like on firefox) and open the menu but not sure if it's worth it.

Apple supports context menus via the keyboard when VoiceOver? is turned on. With voiceover running a context menu is invoked via VO+shift+m (VO command keys is usually control+option). This works for the dijit context menu in Safari 4 so closing as wontfix and updating the menu doc for safari. Not sure how we want to deal with the test file since we probably don't want to have to turn on voiceover (apple+FunctionF5) in the unit tests.

Oh OK great.

As you said we probably shouldn't put this into the automated test because it requires turning on voiceover... and even if we can do that automatically as part of the test I don't think I want to.

(In [22442]) Disable keyboard context menu test on webkit altogether, due to problems running via runTests.html when F10 brings up the native context menu in the outer window, in addition to the close menu in the iframe. Refs #9927.
