Try replacing everything between \begin_body and \end_body with the

It uses an alignat environment with three columns added (raising the total
from the default two to five), leaving the third column empty (so that the
last expressions before \iff align left rather than right).
Close, but not perfect. For the central part we need gather(ed). There's
no escaping it. Compare:

centered formulas + \iff
Hi, I'm using Lyx 2.1.4. I'd like to write a bunch of inequalities with an \iff on the right side. The inequalities should be centered, like this: <=> <=> <...> The problem with gather is that it only allows one column. If I insert a gathered environment and add a second column, it doesn't work. Wouldn't it be simpler if Lyx let users decide the horizontal alignment on a column-by-column basis? I guess there are technical difficulties in doing this...

Lyx 2.2 and spaces before displaymath
Hello, I wrote a document in Lyx 2.2 and I noticed that I had added extra empty lines before displaymath elements all over the document. This happens when one hits return before pressing Ctrl+Shift+M. Did this happen in Lyx 2.1.4 too? I never noticed. Should this behavior be considered a feature or a bug? Kiuhnm

pseudocode
Hello,
I'd like to insert some pseudocode in my paper using my own style. For
instance, I don't like "endwhile", "endif", and similar.
Here's an example of what I'd like (use a monospaced font):
for $I_1$:
for $I_2$:
$X_{I_1}\leftarrow
I usually use the enumerate environment (with the enumitem module) for
this but this time I got the error "nested too deep". And, frankly,
enumerate is not very convenient for algorighms because one needs to
change the spacing, hide the labels, etc...
Basically, I just need a way to indent lines the way I like and be able
to use math.

\prescript from mathtools seems to work well. It'd be great if leftside
prescripts were supported directly by Lyx.
Kiuhnm
Just type them the same way you would super scripts in LyX. If you
wanted 5 to the power of two it would be 5^2 if you wanted a 2 as a
prescript then ^2 5 or use the underscore for subscripts.That's what
works for me.
That's not a good solution because the spacing is wrong. Compare:
\begin_body
\begin_layout Standard
\begin_inset Formula
\[
f\times^{5}g^{4}\neq f\times\prescript{5}{} g^{4}
\]

I'd suggest you file an enhancement request for this at lyx.org/trac/.
It may not be too difficult.
What about using a LyX macro to encapsulate \prescript?
It works quite well. The trick is to use \prescript for the LaTeX part
and {}^{\#1} for the LyX part, so it's easy to edit.

The LyX-Code environment lets you indent with spaces, and you can use math freely. The monospaced font is merely a default, you can override it with a character style: Mark your algorithmic text, Edit->Text Style->Customized... Select Family:Roman or Family:Sans serif according to taste. If you write lots of such algorithms, then the way to go is a custom document class with LyX-Code redefined to the font you like. A custom class take some work to set up, compare to the work of changing the font on every algorithm. This will do! Thank you. Kiuhnm
