I mentioned to Margus in EN about how the Enter key interacts with the Chat box when the Market window is active. Margus made a slight adjustment, in that it doesn't open chat anymore on the first press of Enter, but it does if you press it again. Also, the cursor doesn't stay active in the market box.
With /wiki, all enter keypresses are confined to the /wiki window. chat doesn't open, and i don't have to re-click the input box for each query.
Please, Please, please fix the Market window to be much more like the /wiki window.
