And finally, on LyX OS-X related question:
How can I use the "Ctrl" key in LyX key bindings? "C" is
apparently bound to the "Apple/Command" key and "M" is bound to
the "Alt" key. All this makes sense, of course, I would just
like to use the "Ctrl" key as well.
I believe this is a Qt/Mac limitation and so out of our control.

When you say "use Ctrl as well", do you mean you want Ctrl and
Command keys to be switched? If that's what you want, it requires
modifying the file
src/gui/kernel/qkeymapper_mac.cpp
in the qt-mac-opensource source distribution. I've done that and
have compiled LyX 1.5.3 with it. That way, LyX uses Apple/Command
as a meta key, and Ctrl as the control key. I can put that binary
online, and post more details on the QT patch, if anyone is
interested. I hadn't done that because I haven't had a chance to
work with the new version myself yet (my main LyX is still at
version 1.4).

Thanks Jens,
However, what I actually want is to use *both* keys within LyX.
Apparently (according to Bennett) this is not possible because of a
MacQt limitation.
Daniel
Daniel,
yes - I don't think we can have all three modifiers (Ctrl, Apple and
Option) work "completely" independently in LyX. Although Qt defines
all three,
Qt::ControlModifier
Qt::MetaModifier
Qt::AltModifier
as separate values, Lyx doesn't let us use them. The Option key is
somewhat special: unfortunatley, Lyx doesn't recognize the difference
between "Command-w" (key binding for "copy"), and "Option-w". But
_some_ Option-key combinations are caught at a lower level and then
work in a way that the analogous Command-key combination doesn't do.
E.g., "Option-u o" produces the umlaut ö, but "Command-u o" doesn't.
Here is an old reference on this issue:
http://osdir.com/ml/editors.lyx.general/2004-09/msg00207.html
That email was how I started using the patched Qt where Command and
Ctrl are "un"-switched. I'm posting the patched binaries at
http://www.uoregon.edu/~noeckel/LyX/
Starting to test it now, and already found another issue to add to
the list:
The key combinations "M-~S-less" and "M-~S-greater" aren't recognized
anymore. So the xemacs binding for buffer-begin and buffer-end no
longer work correctly. This holds for the official binaries (on Intel
and PPC), and I see the same with my own builds. More precisely, it
still works if I press "Option" as the Meta key, but not if I press
"Ctrl" (for the official binary) as Meta. This used to work in LyX
1.4 - and the new behavior is clearly inconsistent.
