IDEA: a hand to move in a document

[kinkin]

Exercise of style under Windows (XP, for me).
And why not generalize the displacement of a part of an open document (drag) as with the "hand" of Adobe Reader.

i see what you mean, this works in all/most adobe products too, you can use the spacebar as a shortcut.

The Grab n drag addon adds this feature in Firefox and now i can't live without it.
