Push Pop Keymap Syntax

can anyone help me with the syntax to have a new keymap for a certain time and then have it go back to normal binding afterward?

t1....

function keyPressPushed()
{
pushActionMap("MassMedia.sae");
}

Event::Attach(someEventUn pressed, "popActionMap(\"MassMedia.sae\");");

NewActionMap("MassMedia.sae");
EditActionMap("MassMedia.sae");

bindCommand(keyboard0, make, "mykey", TO, "doSomething();");

Last time I popped and pushed I was doing Z80 assembly.

thanks r@ndom!!
