This is actually the method used by MS Word as far as I know, or a reduced dialect of it. It&#x27;s a mix of convenient and inconvenient, can&#x27;t make my mind up about it.<p>All I know is that LaTEX is much, much easier to manage than this jumbled mess...

What I would like is a set of characters and a font that I could use to enter immediately readable math formulae into my text editor, so that I can take quick notes at a conference, or whenever.<p>I can already do it, to some extent, for instance, this is the summation equation from page 5 in the pdf above:<p><pre><code> ₙ ⎛n⎞ (a + b)ⁿ = ∑ ⎜ ⎟ aᵏbⁿ⁻ᵏ ᵏ⁼⁰ ⎝k⎠ </code></pre> But, the scale is off (the summation is too small) and the characters are a mix of sub- and super-scripts and modifiers (in other cases, diacriticals), and multiple characters in the case of the long parentheses. I have to go hunting each of those characters down every time I want to use them, because I&#x27;m never sure exactly what characters are available. And even when I do, I still have to look them up most of the time, because of course I can&#x27;t remember the unicode number for Modifier Letter Small k off the top of my head every time I need it (although by now I&#x27;ve learned the ones for super&#x2F;subscript i and n by heart, mostly)<p>Worse, there is basically only one free <i>monospaced</i> font that will display all of those characters (DejaVu Sans Mono) and even that doesn&#x27;t cover all the symbols I might want to use. For instance, I use the &quot;entails&quot; symbol a lot and that renders as a ⊨ in DejaVu Sans Mono, so I have to put it togehter with what I got: |= or \= for the negative.<p>Each of the methods discussed in the pdf above (as far as I&#x27;ve read in it, which is not too far) are far from ideal. They&#x27;re all markups, so they all require at least some mental rendering. Why can&#x27;t I have a script that lets me write each special symbol as one character, or at worse, a few of them like for the large parens, above?<p>____________________<p>Edit: And you&#x27;ll need to set your broswer&#x27;s font to a monospaced font to see the equation above properly :&#x2F;

Shameless plug I am working on something related. System with nice keybindings which feels sort of allright after 5-10 minutes.<p>The idea is to combine an efficient onscreen structure with key presses typed by the left hand. So press q,w,e, etcetera to select.<p>Currently I&#x27;m looking at MathML and Tex support, would anyone who uses Math daily be interested in UTF-8 support?<p>My instinct tells me that this UTF solution seems like a nightmare.<p><a href="https:&#x2F;&#x2F;htmlpreview.github.io&#x2F;?https:&#x2F;&#x2F;github.com&#x2F;richard-jansson&#x2F;roosevelt&#x2F;blob&#x2F;master&#x2F;index.html" rel="nofollow">https:&#x2F;&#x2F;htmlpreview.github.io&#x2F;?https:&#x2F;&#x2F;github.com&#x2F;richard-ja...</a><p><a href="https:&#x2F;&#x2F;github.com&#x2F;richard-jansson&#x2F;roosevelt&#x2F;" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;richard-jansson&#x2F;roosevelt&#x2F;</a><p>It&#x27;s possible to input into the os, leave a comment of you&#x27;re interested.

I thought the format of the document looked familiar... and then saw &quot;Microsoft Corporation&quot;. I&#x27;ve seen a lot of other documents from them with the same formatting, and it always feels a bit weird to me --- something looks a bit off about the (body) font.

2016? I’m fairly sure I read this (or something very similar) around 2012.
