Keyboard Viewer > Custom Panel shortcut?

Any idea about how to access a custom panel named "Empty", that's inside the Keyboard Viewer?

(besides using several actions to click Find Image)

Used UI Browser to see if I was able to call it using AppleScript, but it was unable to access it, or even the Keyboard Viewer.

Thanks

Progress: Now I'm able to open and close the Keyboard Viewer using the following applescript:

if application "System Preferences" is running then do shell script "killall 'System     Preferences'"
repeat until application "System Preferences" is not running
    delay 0.1
end repeat

tell application "System Preferences"
    reveal anchor "Virtual_Keyboard" of pane "com.apple.preference.universalaccess"
end tell

tell application "System Events" to tell application process "System Preferences"
    repeat until checkbox "Enable Accessibility Keyboard" of tab group 1 ¬
        of group 1 of window "Accessibility" exists
        delay 0.1
    end repeat
    set theValue to value of checkbox "Enable Accessibility Keyboard" of tab group ¬
        1 of group 1 of window "Accessibility"
    delay 0.1
    if theValue = 1 then
        set frontmost to true
        repeat until frontmost
            delay 0.1
        end repeat
        click checkbox "Enable Accessibility Keyboard" of tab group 1 of ¬
            group 1 of window "Accessibility"
        delay 0.1
        if UI element "OK" of sheet 1 of window "Accessibility" exists then
            click UI element "OK" of sheet 1 of window "Accessibility"
        end if
    else
        click checkbox "Enable Accessibility Keyboard" of tab group 1 of ¬
            group 1 of window "Accessibility"
    end if
end tell

Edit:
Ended up doing Find Image, works fine.
