Note: When I say hot string, I mean a string of characters that, when typed, are automatically replaced with a mathematical symbol. e.g. “frac” is replaced with a fraction symbol.
Some hot strings are long and cumbersome, like giventhat, evaluateat, and epsilon. I think shortening these and others to something like “giv”,“eval”, and “eps” would be immensely helpful. Also or alternatively helpful would be a way for users to customize default hot strings to their preference. I use Hypatia to take notes during lectures and cumbersome strings like this can cause me to fall a bit behind.
Also, I’ve used d/dx or partial/partialx dozens of times in a single insert and typing them out that many times gets pretty frustrating (fracdd and fracpartialpartial). Hot strings for those would also be great, like dd and pdd, or ndd and npdd for nth order derivatives.
P.S. Hypatia has been a lifesaver since written notes and Latex tend to be a struggle for me. Keep up the good work!
We have added new features to support partial and higher order derivatives.
As already mentioned, you can insert derivative dy/dx using diff command. We have now also added a similar command for partial derivative pdf. So for example, typing pdf + SPACE will produce:
For the higher order derivative you can just simply move caret after d in the nominator and attach a superscript to it (with ^):
The d symbol can be inserted also directly by typing dd + SPACE. For example, it can be used to produce a better looking integral:
