Is keyboard not supposed to work? E.g. tabbing through the widgets.
When you select text in a textbox, the keyboard should input text. Also, individual menu items have their own keyboard shortcuts. If you're on a PC, it defaults to using the Control key as the "Apple" key. If your on a Mac, it defaults to using the Command key. This option can be changed in the preferences app in the "Set Conveniences" pane.
