How to enable trace() and other INFO display

I am very much a newbie to krpano and have spent half a day searching the forum and cannot figure out how to use the trace() to display INFO about krpano variables in real time. I see the trace() everywhere but when i add it to an xml it doesn't show up. For example I added the follow snippet from one of the threads about action variables. I was thinking this would show the output in a window somewhere. Does nothing when added to XML .
I'm trying to learn by watching what is going on but the examples I have found so far are not above me.
I could use some help

<action name="hello">
trace("hello ",%1);
</action>

<action name="main">
hello(world);
hello(kitty);
hello(Klaus);
hello();
</action>

Ok, that is something I didn't find either. Where is that? (press o for console)

So apparently the actions are not being triggered because if I link to an events code like

<events onkeydown="showlog(); trace('keycode=',keycode); trace('fovmin=',view.fovmin); trace('fovmax=',view.fovmax); trace('fov=',view.fov); main();" />

the actions are triggered and main calls hello. What are the ways to call an action?

<action name="hello">
    showlog();
    trace('view.maxpixelzoom=', view.maxpixelzoom);
    trace("hello ",%1);
</action>


<action name="main">
   
	hello(world);
	hello(kitty);
	hello(Klaus);
	hello();
</action>
