  Are 'alt' and 'opt' different keys / modifiers on some keyboards or
can they safely assumed to refer to the same modifier?

On Macs, they are always the same.

ns-control-modifier and ns-function-modifier are missing.

I will add these.

Have fun with the function key. That wasn't very straight forward on Carbon.

I've been working on a `mac-capslock-modifier', but it requires a
kernel extension, so I wouldn't necessarily implement it in the Cocoa
version.

Will hold off.  Many people map caps-lock to control at system level
so it might not be as important as the others.

Well, there is currently no good way to map it to Meta in Emacs, simply because Meta doesn't exist on the Mac system level. I simply don't think Cocoa provides an API to set the CapsLock button (i.e. turn toggling off).




Is frame transparency available?
Works in Carbon (with transparency patch) like this:

(set-frame-parameter nil 'active-alpha 0.5)

(ns-set-background-alpha 0.5)

It's also an interactive function.  This will be added to the prefs
panel at some point.
A frame parameter makes more sense in some ways, but alpha's really a
property of the background color, which is already a frame parameter,
so...

Doesn't the frame frame (sic), i.e. the window border etc. become transparent, too? I thought the background color is for what is inside the windows (conjecture)..?

I don't think frame transparency is all that important. We have it in Aquamacs, but I doubt people use it much.
