With the great support for the mouse, touch, and graphical interface aids like ribbons incorporated into later personal computers, the need for navigation hot keys was greatly diminished. But there are other hot keys that can be ...

Some assistive technology (AT) programs use MathML or OMML as conduits for generating math speech and braille from math-enabled apps. In addition, they would like to use these formats for editing math text as well as speaking it and displaying it on refreshable braille displays. To this end, the formats need selection attributes that identify where...

RichEdit clients may want to zoom images that the user clicks on. To satisfy this need, the Microsoft 365 version of RichEdit supports the EN_IMAGE notification, which notifies the RichEdit client when the mouse moves over an image or the image is clicked on.

More precisely it was in 1965 that I started using a nifty (for that time) vector plotting program by Grey Freeman at the Yale Computer Center. I was a Yale grad student in ...

The Unicode Standard needs to encode regular and bold math calligraphic/chancery alphabets as well as regular and bold and fancy-script/roundhand alphabets, since chancery and roundhand alphabets are used contrastively by some authors and [La]TeX can support both kinds of letters. In most documents, chancery and roundhand styles can be substituted ...
