Hi,
We have just added support for "PlatformKeyCode" for you in the Beta 11.5, available at:
http://forums.cshtml5.com/viewtopic.php?f=6&t=8006Please note that, as the name suggests, the value depends on the browser. For example, the dash ("-") is 187 on IE and Chrome, but 173 on Firefox. To determine your current browser, you can use Interop.ExecuteJavaScript to check the existance of the following JS variables: window.IE_VERSION, window.ANDROID_VERSION, and window.FIREFOX_VERSION. You can see where those variables are defined by opening the file "cshtml5.js" that is located in the "Libraries" subfolder of your Output folder.
Regards,
JS-Support
