symbolstexworks
Unlike most other TeX editors, TeXworks dose not provide any facilities to find and insert symbols, is there any plugin or any program that can be used in parallel with TeXworks?
I am looking for a program like ''IPA Typing Assistant'' but for math symbols.
It can be used for inserting IPA symbols in all applications easily.
With
\usepackage{cmap}
the two symbols may be associated to U+27E8 MATHEMATICAL LEFT ANGLE BRACKET and U+27E9 MATHEMATICAL RIGHT ANGLE BRACKET. If you want to input them directly, here it is how it can be done:
\documentclass[a4paper]{article}
\usepackage[utf8]{inputenc}
\usepackage{cmap}
\usepackage{textcomp}
\usepackage{newunicodechar}
\newunicodechar{〈}{$\langle$} % U+27E8
\newunicodechar{〉}{$\rangle$} % U+27E9
\begin{document}
\textlangle\textrangle
〈〉
\end{document}
Another choice might be
\newunicodechar{〈}{\textlangle} % U+2329
\newunicodechar{〉}{\textrangle} % U+232A
You can use directly \DeclareUnicodeCharacter, of course, with
\DeclareUnicodeCharacter{2329}{$\langle$}
\DeclareUnicodeCharacter{232A}{$\rangle$}
instead of \newunicodechar.
This should allow to copy and paste the symbol from the PDF viewer, but it seems that the code of the copied character is viewer dependent, when \textlangle and \textrangle are used. :(
Thanks to Martin Scharrer for having suggested improvements to the answer.
You can use the braket package for this kind of thing.
\documentclass{article}
\usepackage{braket}
\usepackage{amsmath}
\usepackage{bbold}
\begin{document}
\[
\mathcal{H}=\Set{ h(x)=\sum_{i=0}^{k-1}a_{i}x_{i}\mod m\ |
\ a_{i}\in\mathbb{Z}_{m^{k}}}
\]
\end{document}
It defines a \Set macro which automatically puts its contents in variable sized braces, and any instance of the | symbol inside will adjust accordingly. This solution also has the advantage of making your source code more semantic.
Best Answer
It is because TeXWorks philosophy is different from any other TeX editors that you have seen. Its main objective is to be simple and easy to use.
If you're really looking for such a feature in a TeX editor, maybe your best bet would be to switch (at least temporarily) to one of these other editors.
