Evaluating expressions in Visual Haskell

Hi, I apologize if this question has been asked before, but I couldn't find an FAQ or the answer online. Does Visual Haskell have support for evaluating expressions? I tried a few things (like highlighting an expression, rightclicking, and looking for "evaluate" option) but couldn't find anything. If this feature is missing, is it planned? Also, what is a good way to do this together with Visual Haskell? I could, of course, open an interpreter in a command window, load appropriate modules, and evaluate expressions from there but is there a more "integrated" way? Thanks, - Slava Akhmechet
