How to make a macro for summon force attack

hello wel the subj says it all.
btw Tried /useforceskill summon attack.
And yes if i press ctrl and summon attack of he goes :).
But wanna make a macro for quick pvp attack. :)

1. I put the summon attack button in bar 9, slot 12

2. /useshortcutforce 9 12
