I'd like to control the Latex fontsize in the notebook. In the first cell, I placed:

%html
<style>.MathJax {font-size: 200%;}</style>

... and in later cells' view() outputs the individual characters/symbols increase in size but the positioning/spacing gets all spread out and ugly.

What's the right/easy way to increase the latex fontsize in Sage's notebook and still have it look good?

Right click on any rendered Latex expression and you will get a MathJax menu. In that menu, you will get the option to scale all math, or zoom with some trigger, etc.

Is this in the notebook documentation? It seems like this would be useful on the "Help" page, not (just) in the reference manual, though it could be good there too...

Well, it is in the MathJax docs :) I had once implemented a way for this menu to popup on double click, just like in jsmath the latex would popup on double click. Not sure if there is any interest in that behavior anymore.

Thanks, I hadn't tried right-click. Is there an easy way to control this programmatically on a per-cell basis? The right-click options seems to affect the entire worksheet.

Does something like this help? html("this is $%s$"%(LatexExpr(x^2 + 2))) It is quite fragile though. And the `` tag is also deprecated for years, and is not available in HTML5.

Thanks. That may be enough for now. Would MathJax need some visibility into the javascript to get more/better fontsize control?
