I had the same problem a ways back and came across this AppleScript on
the old boards. Just add it to your catalog or actions folder, type
in a word to the first pane and bring up this script in the second
pane and run it. Your word should be looked up in the system's
dictionary. Sorry, I can't remember who originally posted this. Hope
it helps!

keystroke "f" using {command down, option down}
keystroke "a" using command down
keystroke lookup
keystroke return
end tell
end process text
