Switching between drawing and modelling

Does anyone know of a way to switch between drawing and modelling inside a journal?

I've had partial success with SendKeys.SendWait("{F12}"), but I had to assign the shortcut key F12 to the modelling application. By default, the modelling application has a keyboard shortcut of ctrl+m, but I could not get that to work. For some reason, only the function keys worked for me when using SendKeys.SendWait().

Cheers,
Ian

Starting with NX 8 there is the ApplicationSwitchRequest method.
