First, if you're on Leopard 10.5.x, be sure you have the "action" or "gear" icon in your Finder's toolbar (Finder > View > Customize Toolbar).  If there's no toolbar, click the lozenge at the upper-right of the Finder window's title bar.  If the Action icon isn’t there, click View > Customize Toolbar from the menubar and drag it in.

Then Enter Time Machine, locate and select the desired item in the Finder window as in question #15  and control-click (right-click) it (on Leopard, click the "gear" icon), then select the Restore <item selected> to ... option.
