I come from a C++ background and prefer using double quotes for
strings and single quotes for characters. There really isn't a big
difference. Many of your questions would be answered by reading the
Lua manual: Snippet files
are actually Lua code.

It's a multi-line string. I need to get around to converting more of
my snippets to use those to make things more clear.

In general you should keep pressing the tab key until the snippet is
done, not just use the arrow keys or mouse to move it. When all the
tab stops have been hit that "mustard" line should go away. It's a
bookmark set to indicate the end of a snippet.

I wrote a snippet introduction here:
