Feature: invert select/content select

Many - if not most - web pages follows the "container element" pattern: 
A page will be split in e.g. 3 sections, each with their own container 
element. Inside the container elements, one places the actually "stuff". 
Further, it is also a  common "pattern"  to create new pages based on an 
old page: The old page becomes a template for a new one.

Now, with the F2 command, one can select the parent element. Or, rather, 
first one selects the entire element that one is currently working 
inside. Press F2 once more, and youselect the parent element.

What would have been awesome was a "invert select" tool, or perhaps 
rather  a "select content" tool.

Then, if I selected <div id="container">etc</div> with the F2 selector, 
I could thenafter press - for exampe Alt+F2 to select only the content 
of the container element. Then I could delete the content very easily 
and fill the container with new "stuff".

This would have been a terriffic tool to have when working with 
templates, both existing pages used as template as well as "real" 
template pages.

What do developers and other users think?
