Keyboard Operator Shortcuts

The previous post introduces Hermann Klinke’s math input notation, which he developed to speed up entry of equations for real-time note taking in OneNote. The post is followed by a very interesting set of comments comparing high-speed, and yet easy-to-remember, input sequences. Some of these involve hot keys and some can be done with math…

Klinke’s Streamlined Math Input Notation

Hermann Klinke has designed and instrumented an input notation on top of the Microsoft Office math facility that you may want to try. It significantly reduces the number of keystrokes needed to input mathematical text. His motivation is to have a way to enter equations in real time while taking lecture notes. He has documentation…

Math Accents

Accents are quite common in mathematical text. For example, in physics one uses one- to four-dot accents to designate the first through fourth time derivatives, respectively. Primes are often used on integration variables. Transforms can be designated by tildes and averages by overlines. While accents are usually applied to a single base character, they can…

Office Insert Symbol Dialog

This blog post describes a cool insert-symbol facility built into Office applications like Word, PowerPoint, Excel, and Outlook. The facility is handy for locating mathematical symbols as well as other characters. And with the developments in Unicode these days, that means a lot of symbols! Recently the Unicode Technical Committee and the ISO WG2 Committee…

Sans Serif Mathematical Symbols

Most mathematical documents and books use fonts with serifs, such as Times Roman. However mathematical expressions can also be displayed with sans-serif letters, such as the font this post uses. In fact, sans-serif letters are used sufficiently often in mathematical typography that six sets of them are included in the Unicode Mathematical Alphanumeric Symbols. Further rationale…

Rendering MathML in HTML5

As you can see in this document, Presentation MathML is part of HTML5. This is very exciting, since HTML5 is becoming the primary new web standard format. You might think that this would automatically make it easy to render MathML in a browser. In fact, FireFox does a decent job of rendering MathML, having incorporated…

Math Keyboard Shortcuts

Nali commented on the post Office 2007 Math Editing/Display that it would be nice to have keyboard hot keys to switch between Professional and Linear format (build up/down), and between Display and Inline mode of equations. This is a great idea especially for those of us who like to use keyboards to speed up math…

NINCH and EMU

People have been asking about a couple of acronyms fairly often these days, so here’s a blog post on them. They are described on the web already if you type the right queries, but a little more motivation might be useful. The acronyms are NINCH for “no input no change” and EMU for “English Metric…

Two Math Typography Niceties

Roughly eight years ago, some colleagues and I had the good fortune to spend an extraordinary afternoon with Donald Knuth, the primary author of TeX, at his home on the Stanford University campus. Among many things, Donald showed us how he uses TeX to typeset his computer-science papers and books exactly the way he wants…

Equation Arrays

One user (Leperkawn) commented “There is basically no documentation on the \eqarray command so I’ll post a quick example that I had to figure out from trial and error.” Before looking at his interesting example, here’s the text in Section 3.19 of the linear format paper describing how to type in equation arrays: To align…
