[Typo3] Back button

["Jesús H."]

Hello list,

This seems to be simple but today seems not to be my day in front of 
TSRef. I am tring to archieve a back button that goes to the parent page ie:

A--|
    |-B
    |-C
    |-D
E--|
    |-F


For example if I am sitting in C I want the back button to go to A... 
I've tried with T menu limiting it to one item but of course if I am at 
F then will show only A since is the first item at level -2.

Any hints will be appreciated.

Best regards,

Jesús H.
