[ydl-gen] How to change control keys on Keyboard?

[H. Apfel]

Now what I want to do is to swap the Apple, control and alt keys on 
the keyboard. The most obvious way (at least to me) would have been 
to redefine the the behaviour by swapping the keycodes within the 
keymap and loadkey-ing it.

However, doesn't work.

Is there anything special I've got to do beside loading the new 
keymap? In an old mat there was a 'alt_is_meta' command, which wasn't 
documented in the man-pages, so I'm not sure whether this has 
something to do with the misfired reassignment of the keytable.

Thanks for any  sugggestions.
