Create a script event in the keyboard mapping menu and assign a shortcut key to it.
The script would be this:
dim fb as xpOutputFramebuffer
dim scene as xpScene
dim scenegroup as xpSceneGroup
engine.GetOutputFramebuffer(0, fb)
fb.GetSceneOnLayer(0, scene)
if scene.IsGroup then
scenegroup = scene
scenegroup.stop
end if
This will stop the crawl/roll on Framebuffer 1 Layer 0.
