@Holo So you have basically stumbled on an important problem in both practical and theoretical computer science, namely prefix-free encoding. =)
I'm not too sure why you consider putting spaces after the hotstring to be a problem, since you need to do that when typing LaTeX anyway, so it will feel very natural to you. No?

@user21820 yes, but still! Think about the amount of energy I'll waste in a life time!!
@user21820 :P
@Holo Lol! You will save a lot by using shorter command names. For example I use "\wi" for "⊆" and "\co" for "⊇" and "\imp" for "⇒" and "\eq" for "⇔".
Good point!(although I can't use \co, I have \coprod command for disjoint union)
6 char is too long. =P
I also have \equiv for equivalent (3 too long!)
I'll have to go through everything I have done today!
You mean go through all your hotstrings? Reminds me of an XKCD...
Oh there are two of them:

Too true...
The chart says you can spend 2 hours on it.
@user21820 especially this one
@user21820 sounds about right
I have to go catch a bus now! See you later @user21820
@Holo See you later!

Hi
In this question, I don't know how to show if they are theorems. I know I should use the axioms, Modus Ponens and Generalisation rules which are:
