To type 'root' you should use sendkey r sendkey o sendkey o sendkey t Multiple keys in sendkey is meant for multiple keys pressed at the same time, i.e. ctrl-alt-del, not for sending key sequences and typing words. > People want to panic windows by sending Ctrl-Scrool-Scrool > http://msdn.microsoft.com/en-us/library/windows/hardware/ff545499(v=vs.85).aspx > But current events order doesn't work. sendkey Ctrl-Scroll sendkey Ctrl-Scroll > In physical keyboard.

But it is neither upstream nor in my local input branch. And I can't remember what happened :( Marcelo, any clue? Maybe I should just re-queue it ... The input-send-event gives you fine-grained control about the exact input event sequence and it can handle your use case without problems. cheers, Gerd
