Not with the tools at our disposal, no. But see below for what you  
can do now.

Very well, but use at your own risk. For this, open the Bundle Editor  
(⌃⌥⌘B) and create a new language. Give it any name you like and  
put it in any bundle you want. Then, in the big text area on the  
left, place the following text:

{	scopeName = 'text.tex.latex.mylatex';
	firstLineMatch = '^\\documentclass(?!.*\{beamer\})';
	fileTypes = ( 'tex' );
	foldingStartMarker = '\\begin\{.*\}|%.*\(fold\)\s*$';
	foldingStopMarker = '\\end\{.*\}|%.*\(end\)\s*$';
	patterns = (
		{	name = 'support.function.myfunctions.latex';
			match = '(\\)(my|commands|here)\b';
			captures = { 1 = { name =  
'punctuation.definition.function.latex'; }; };
		{	include = 'text.tex.latex'; },

Set a key equivalent for this language. Make sure to press the button  
that says "Test".
Now, set this as the language in one TeX file. This should be  
respected in all other files.
Now, the commands:
will be recognized as support.function.myfunctions.latex
You can change that by changing the line with the name.
You can add commands to this list by adding them next to here in the  
match line (well, you probably want to remov e those three first),  
separated with a vertical line (|).
For instance:
match = '(\\)(this|list|of|commands|)\b'
would allow the use of the commands \this, \list, \of and \commands.

Adding environments is a bit more work.

One of the things I hope to add to the bundle soon is the ability to  
quickly change between equation styles. I.e. you are in an align  
environment, and you press a button and it becomes a split  
environment. And so forth.

We try to provide a service ;)

Well, the closing tag will just close the one above it. You also want  
to open one. One could probably duplicate and modify the closing tag  
command, so that it instead adds a \begin{env} too. So it would be a  
"split environment" command. Might do that actually.

Sorry,  I should have said: The size of the LaTeX Help file. I'm all  
for creating other sources of assistance, like howtos and cheatsheets  
and stuff. The help is supposed to be for reading by someone new to  
the bundle, possibly even relatively new to LaTeX, who needs to get  
started getting things set up and learning the basic commands.

I was thinking of two different kinds of cheatsheets, one pdf that  
would fit in a page and could be printed, and one html/markdown,  
longer and with more explanation.

I would say let's try to create some more specific "HowTo" questions,  
and then we'll see about answering them. I'll get started on the  
cheatsheet for now.
