- Turn on "Enable Advanced Features" in Quicksilver
- Enable proxies in Quicksilver preferences: Under Catalog > Quicksilver, turn on “Proxy Objects”, “Internal Commands”, and “Internal Objects”.
- To access menu items (and enable the Show Menu Items action), go under Plug-ins > All Plug Ins and scroll down to turn on “User Interface Access (+)”.
- Make sure you have “Enable access for assistive devices” turned on in System Preferences for the entire OS
Once you have this set up, you can get to the menus by choosing Current Application as the noun and Show Menu Items as the verb. It gives you a list of all the leaf menu items in the current application.
That's sort of cumbersome, so I set up a trigger to make it easier. I created a Quicksilver trigger (for me, keyed off the ALT-ENTER key chord) that automatically launches the list of menu items in the current application. Now, as I'm Mac-ing along, the key chord gives me Quicksilver access to all the menu items, which is even easier than the CTRL-F2 trick shortcut that used to be my favorite.
