How do I get undersets not to make the spacing of the equation wrong
when the width of the underset is wider than the equation?
doing $a+\underset{description}{underbrace{b}}+c$ comes out as
a+ b +c

instead of
a+b+c

thanks
I suspect what you want is the following (in a math inset):
1. type \underset (space);
2. in the upper box of the inset, type \underbrace (space);
3. enter the formula in the innermost inset;
4. enter the description in the bottom space.

That is what I'm doing, the problem is that the spacing is all wrong.
The reply ruined the spaces so I'll use underscores instead. Using your
method I get
a + _____ b ______ + c
_________ }
_____ description
While what I want is
a + b + c
___ }
description
here, _ are spaces and } denotes the underbrace (which is supposed to be
only under b)
I remember seeing a solution a couple of years back or so on this list
so I know it's possible, but can't find it anymore.
Putting the underbrace under just the b is easy. If 'b' is replaced by a
sufficiently long expression, the brace will stretch to the width of the
expression, but if 'b' is literally one character, the brace will be
wider than b. Are you asking how to make the brace narrower? I don't
know if that can be done.
If you're doing what I wrote before (but with the brace only under b)
and there's extra space surrounding b that annoys you, I suspect it's
from the brace, not from the description.
As a side note, I noticed that when putting the brace under b only,
sometimes the space between + and c was short-changed. That can be
corrected by inserting space manually.

The behavior is to expand the whole block of b, underbrace and description to
the width of the block. The brace is as wide as b, not as wide as the
description (I'm actually using an arrow in this case, but it doesn't matter),
my problem is with the bock width, not the brace width.
I ended up inserting negative vspace, although I seem to recall that there was a
more "correct" solution to the problem.
