Bookmarks to render MathJax

"start ChatJax" installs MathJax and starts a loop that renders LaTeX as needed.
This is intended for use in chat, where the contents of the page are not static.
Reloading the page will stop the loop, so the bookmark needs to be run again.

"render MathJax" installs MathJax and renders LaTeX once per execution.
This is intended for use on web pages where the contents of the page are static.

Installing on Troublesome Mobile Browsers

menu, add a bookmark as instructed below. Open this bookmark from the chat
page to start ChatJax.

Using with Chrome on Android

Evidently, Chrome on Android does not remember the current page when
opening a bookmark from the standard bookmark menu. The bookmark can
still be used; however, the procedure is a bit more involved than simply

Go to the Search bar and start typing the name you've given to the bookmark
(e.g. "start ChatJax"). The bookmarklet should appear in the list of items
found. Open that item and ChatJax should start running on the current page.
