[orca-list] How to access all installed applications from mate desktop?

[austinAustin quesada <austin arq gmail com>]

Hi all. I'm wondering if there is a keyboard shortcut in orca to do
this? I no that alt f 1 will bring up the application categorys, but
i'm not sure how to access all installed applications, especially
because i know sometimes that an application can be installed but not
put in the proper place in the menu. Thanks for any help.
