Try, within an aligned environment, entering a standard inline math 
environment.  This will give you a blue rectangle, and if you type 
something there, it will be in standard Roman text.  It is a \text{} 
environment.   Alternately, heck, you can type  \text  and hit the 
Enter key; you will then be in the text environment you want, but I 
have enter an inline math environment linked to F10, so I just hit 
F10.  You can leave that environment by moving the cursor.


This is normally bound to Ctrl-M. In math, it has the effect of 
introducing a text box.

Re: Equation annotations in a multiline equation

[Abiel Reinhart]

I'm able to type plain text as you've suggested but I'm still unable
to get the alignment and spacing right. I can  type text to the right
of an equation on a given line, spacing it out from the equation using
something like \quad. However, then the annotations from different
lines of the equation won't necessarily align. Alternately I can add a
column to the aligned environment. That takes care of horizontal
alignment but unfortunately then I run into problems with spacing, as
there is little spacing between the annotation and the math part of
the equation. This can sometimes be solved by adding a blank column to
the aligned environment, but in other cases the blank column doesn't
seem to do much and may in fact affect the alignment in other columns.

Re: Equation annotations in a multiline equation

[Abiel Reinhart]

Thanks, after pasting in the text and then examining it I was able to
figure out the correct approach. It appears my earlier alignment
difficulty stemmed from placing the equals sign in its own column. Now
I create a four-column structure in the align environment, with
equation= in the first column, equation in the second column, nothing
in the third column, and the annotation in the last column. This gets
me exactly what I had in pure LaTeX, which makes sense.

The problem really is in the default alignments that AMS-LaTeX uses 
here.  I don't know offhand what the rules are supposed to be, but the 
problem is that some of the columns are right-justified, and others are 
left-justified.  I'm sure that the algorithms are available somewhere.  
You placing the = in the first column, rather than in a column by 
itself, changed the count of columns, and thus the justification.


The justification is different in LyX than it is in the output, which 
might be something to worry about in the future.
