Often, certain symbols in mathematics denote different things in different fields. Is there any sort of ordered list that will tell you what a certain symbol means in alphabetical order by the symbol's alias in LaTeX, perhaps with the way to pronounce it out loud? 


I'm thinking of something like this [Wikipedia page](http://en.wikipedia.org/wiki/Table_of_mathematical_symbols) but more comprehensive and usefully ordered by LaTeX alias (The one on wikipedia has very few symbols, and I am familiar with all of them already). The problem is that when you want to find the meaning of a symbol, there is no way to search on google (because google has no support at all for searching for symbols). Oftentimes, I'm forced to ask someone around the department what it means or how to say it out loud. 


For example, I'm trying to find the meaning of the symbol $\uplus$, but I have no way of finding out what it means. Also, for the longest time, I couldn't figure out what to call $f\_!$ or $f^!$. How should I know that they're called "f lower shriek" or "f upper shriek". 


So for the question: Does any such list exist for either pronunciation, meaning, or both (aside from the one on Wikipedia that I just noted)?



Mathematical symbols, their pronunciations, and what they denote: Does a comprehensive ordered list exist?
Comments suggest this ...

However, a designation like "rightwards arrow above reverse tilde operator" doesn't really answer the question here, does it?
