Let us say you are shopping for clothes and one of the people in the section approaches you and asks "kommen Sie zurecht?" or something like that.
How would you express "oh we're just taking a look", "looking around".?
The literal translation, which works perfectly in this case, would be:
Danke, ich schaue mich nur um.
The verb in question is umschauen.
(I think this works with umsehen and umgucken as well, but as a Southerner, I don't use those verbs.)
For additional ways on how to say just, see this question.
