Revlet - how to get back to the main stack from a substack?

[Keith Clarke]

Hi Folks,
I'm using 'go to stack "substack" in the window of me' to navigate to substacks in a revlet but can't seem to find a suitable script for a 'close' button on the substack to return to the main stack. The following lines are ignored:

'go to stack "<main-stack>" in the window of me'
'go to stack "<main-stack>"'
'go back'

So, what's the secret formula? ;-)
Best,
Keith..
