Dumbledore grasps Harry's intentions, apparently by legilimency:

"You will take Harry back to school, Hagrid," Dumbledore repeated firmly.
"Take him right up to Gryffindor Tower. And Harry--I want you to stay 
there. Anything you might want to do -- any owls you might want to send
--they can wait until morning, do you understand me?"
"Er--yes," said Harry, staring at him. How had Dumbldore known that, at 
that very moment, he had been thinking about sending Pigwidgeon 
straight to Sirius, to tell him what happened?

--GoF ch 28

A non-verbal spell with an interesting effect:

Voldemort slipped one of those unnaturally long-fingererd hands 
into a deep pocket and drew out a wand. He caressed it gently too; 
and then he raised it, and pointed it at Wormtail, who was lifted off 
the ground and thrown  against the headstone where Harry was 
tied; he fell to the foot of it and lay there, crumpled up and crying.

GoF ch 33

Of course it doesn't prove anything, but here we have direct canon
where Harry's concrete intention is communicated to Dumbledore
without words, and of a nonverbal spell that picks someone up
and throws them into the air.
