Thanks for this. I learned more from your response that from a lot of 
googling and reading man and info pages.

 !     add    Lock    = Caps_Lock !! I want this to be Hyper_L . Will this 
conflict with your Mod4 assignment below?

>     add    Control = Control_L    Control_R

!     add    Mod1    = Mode_switch    Mode_switch !! This I don't understand 
at all. Is it the M$ Menu key?

!     add    Mod2    = Meta_L        Meta_R  !! I don't need this since I 
don't have a Meta key, right?

This keycode method seems like the easiest way to swap keys since I can get 
the keycodes from xev. Are the above "clear" and "add" lines still needed? 
In my /etc/X11/Xmodmap file (all commented out) I read:


! keycode and keysym remapping should generally be used only if the X
! server config file has been configured to disable the XKEYBOARD
! extension

Where is the server config file? Is this something I have to worry about or 
can I just add these lines to that file? :

clear Lock
!.
!. maybe other expressions
!.
add Lock = Hyper_L !! Is that meaningful?

keycode 66 = Hyper_L !! is this needed even with the above add Lock expression?

keycode 37 = Super_L
keycode 115 = Alt_L  !! It says Alt on the keycap.
keycode 64 = Control_L
keycode 113 = Control_R
keycode 116 = Alt_R !! Again that's on keycap. Can't I just say alt-is-meta 
or something somewhere?

keycode 117 = Super_R
keycode 109 = Hyper_R

I read that there can be eight columns but that most apps don't support 
beyond four. Does Emacs? Could I globalsetkey something to [(shift control 
alt super hyper h)] ? Of course this would be difficult to touch type unless 
 all keychords that included the shift modifier and at least one other 
modifier were made sticky. The whole point of this for me is to be able to 
touch type most keychord combinations.

In Fedora 8 this was in /usr/include/X11/keysymdef.h

I want to do all this sort of thing with Emacs (leim) input methods.

Thanks again. If you don't have time to answer this I can probably figure it 
out with some (a lot) of experimenting but I don't know what's safe and 
what's dangerous.
