HELP - xml code to run Launcher option or external application from custom menu?

Hey all

My coding experience is limited, but I'm trying to customize the xml of Confluence to make Google Chrome launch from the home menu screen. I've created a menu item for it but the best I can do is run Launcher, and select Chrome from there. ie:

<onclick>ActivateWindow(Programs,plugin://plugin.program.launcher,return)</onclick>

Can anyone tell the code to launch Chrome directly, rather than linking to Launcher first? I figure it could be done either by linking to Chrome within launcher, or linking to chrome as an external application.

Thanks!

I could link to Chrome externally with something like this:

<item id="15">
<label>WWW</label>
<onclick>XBMC.System.Exec("C:\Progra~1\XBMC\www\op era.exe")</onclick>
<icon>special://skin/backgrounds/network.jpg</icon>
</item>

However, I'm running XBMCLive and have no idea what to put in place of "C:\Progra~1\XBMC\www\op era.exe". I know that the application resides in /opt/google/chrome
