Formula: double arrows for chemical equations

[theyogre]

Version 5.0 Math

Is there a way to add harpoon arrows into formulas? I use TeXMaths extension, currently, but it is no longer being supported.

It would be awesome if there were a chemistry subset in the formula editor. Two features that seem minimal but would be very helpful would be:

1. adding harpoon arrows U+21cc U+21c0 U+21bd (or U+21bc)
2. a simple way to allow chemical symbol text to not be italicized

Many other useful formatting features are already present.

Perhaps can help Catalog, with it you can add symbols to use from the font.

Thank you. That’s a helpful start.
