RE: Re: How do I pick out the expression under a radical?


If you want to do it with the mouse, it's not that difficult.  I click
within the part I want and double-click until the part is selected.
(Each double-click expands the selection by one level of nesting.)  Then
push Ctrl-C, click where you want to put the result, and push Ctrl-V.

Does that help any?

GRAY:
    This points up the need, which I've been aware of for years, to be
able to select any part of an expression and drag it to a new line for
further processing. Mathematica and the other CAS I'm familiar with are
still
pretty much stuck with a command line interface. They need a true
GUI with extensive interaction.
    When I can see on the screen exactly what I want to do, why
should I have to type a bunch of stuff in to access what I want?
    Maybe we'll see this in version 5? 6? Never?
