I am using a new iPhone remote control called iRule to control my home theater, including Media Center 15. Using the new commands recently introduced in MCWS, I can control Media Center 15 through a network IP connection in Theater mode with buttons on a remote control page. iRule also lets you embed URLs in pages, and I have embedded a URL pointing to Webremote, so on that page I can control Media Center 15 using WebRemote. But missing are the usual web browser buttons for going back and forward one web page. I've made buttons for back and forward on the part of the iRule page not dedicated to the embedded URL, and am trying to assign them the usual browser keyboard shortcuts for back a page (Backspace or ALT+Left) and forward a page (Shift+Backspace or ALT+Right). But I don't know how to assign the target or focus for these commands to WebRemote rather than the Theater Mode window. Is there a way to do this?
