I think that there's a bug for this in trac. Yes:
I think that it actually starts the paren blinking as soon as the
insertion point gets drawn/starts blinking, but the paren blinks
in the wrong phase relative to the insertion point.

I think that cmd-. works if either a listener window whose listener
is in a break loop or a backtrace window is active.
It could probably be made active if an editor window is foremost
and that editor has enqueued something to a listener that caused
the listener to enter a break loop ... I dunno.
I guess that it could also be active if -some- listener is in a
break loop, but most of the menu items related to controlling
a listener process are really "targeting" the listener process
associated with a particular listener window.

It's synthesized (there really isn't a "Monaco Bold"); there -is-
a Courier Bold (that's antialiased and doesn't look as smudgy.)
But yes, there should be some way of selecting the style used
for listener output.

Meta-. should work pretty well; I don't understand this. (Maybe
it's not picking up the symbol, or doesn't find symbols defined
in buffers that don't have filenames associated with them ?)
I didn't remember what keys macroexpand and macroexpand-1 were
bound to, so I did (in an editor, not a listener window):
echo area prompted for Help: , I typed "a" for "apropos"
echo area prompted for "Apropos what:" (in so many words), I typed
A popup window showed defined editor commands that contained
"macroexpand" in their names and the keys that they were bound
to. (Not much better than "better than nothing", but better than
nothing.) Note that there is a bad bug related to typing to
one of these popup windows, and I tried this in a listener
and the listener went comatose, apparently unsure as to whether
the main view or echo area view was active.
eval-buffer used to be bound to Cmd-H, which now invokes "Hide
Application". If there was an "eval buffer", it'd pretty much
have to have a command-key equivalent that didn't conflict with
that ("Hide Application/cmd-H" is an aqua standard thing.)
Backtrace is cmd-shift-b. If there was a font menu, cmd-b would be
"Bold". cmd-shift-b is active if the "target" window is a listener
and that listener thread is in a break loop.

Don't understand this.

People who don't like it can set a preference.
It helps to get feedback, but (if you can) please create an account
for yourself (this partly discourages spam) at
http://trac.clozure.com/openmcl and enter bugs there.
It's also really desirable (if you want to use the IDE regularly)
to try to stay up-to-date via CVS and rebuild the lisp regularly.
(if this makes no sense, we'll try to ensure that something somewhere
accurately documents the process and refer you to that.)
