This is a pretty basic question, but i tried using \n and ^M to put a
newline, or carraige return, into an alias, and neither worked.
How is this done? Or is it? Also how can i put a 'control-whatever'
sequence into an alias? I'm using zsh 3.0.1.

zsh% alias this_has_a_newline='echo this
quote> echo has a newline'
zsh% this_has_a_newline
this
has a newline
Same thing should work for any control sequence; just put it in quotes.
Notice that in the sample above the newline was taken as a command
separator. That's probably not what you mean, but since you didn't
say why you want to include a newline or control ...

Thanks. This works fine -- all I wanted was to be able to do something like
hit 'c <return>' to clear the screen and have a filenames-only listing of
the current dir at the top of the screen.

I was wondering more about what chars you'd use within an alias to represent
'control-'

Well, it serves the purpose. If there's a better way, I'd be glad to hear
that, too.

There isn't any special syntax for that. You just have to put the control
characters in as themselves.

I'm not sure I understand. I know it would be very useful to be
able to put into aliases things like:
1) a return at the end of the alias (so that I can type, say, a one-letter
alias and have the command, or series of commands, executed without having
to hit <return> after I type the alias.
2) a control sequence, like, say, <control-L> I don't know what you would
put in an alias to make a control sequence. What would be an example? What
would one look like?
3) what would be the representation of any control character -- <return> ,
<tab>, <control-whatever>, <esc> -- how is any of these put into an alias?
Maybe if one wants to use such things that means it's time to start using
small scripts.
i guess I'm looking for a sort of QuicKeys for zsh . . .

This wouldn't work anyway.
Aliases aren't interpreted until command execution, which doesn't happen
until you hit return. What you want is "bindkey -s".

What it looks like would depend on what editor you were using. If it's
the zsh line editor, it "looks" like ^L, but you type <ctrl-V><ctrl-L>
to insert one. You can't type the two characters `^' and `L' and have
them be interpreted as <ctrl-L>. The <ctrl-V> means "intepret the next
thing I type as simple input, even if it would otherwise be an editor
command." That's what I mean by "put the characters in as themselves."
Characters entered in this way normally should be part of a quoted string.

Same way.

Shell functions.

You definitely want "bindkey -s".
