Sending three keys at once with Send()

I'm trying to have a script hit: alt + shift + k

This is what I have and it isn't working

HotKeySet("!q", toTableOfContents)
HotKeySet("!w", toSelectedTab)
 
func toTableOfContents()
   Send("!+k")
EndFunc
 
func toSelectedTab()
   MouseMove(2690, 300, 0)
EndFunc
 
while 1
   sleep(100)
wend

I literally had to delete the code block and retype it in autoit tags before I was able to type after it. And this time it did not delete the content. So not only is the forum buggy, it's inconsistently buggy which is far far worse.
