Hello,
I'm running lyx-2.1.3 on a 64 bit Linux box (Gentoo; up to date; except
that the kernel is 3.12.13-gentoo).
With all lyx-provided math packages set to "load always", including
specifically amsmath and mathtools (and with lyx restarted) I still
only have access to two of the extended horizontal arrows: xleftarrow
and xrightarrow; not to any of the others listed in the math help
document; most importantly for me at the moment: "xrightleftharpoons".
This seems to contradict what the math help doc says in section 6.1.
Help?
Thank you
Elbert Branscomb
