Ah.. sorry, I think I have heard too many complaints about the option
+ arrow key combination ;-)

In that case, this is all it takes:

remove Mod1    = Alt_L
add    Mod1    = Meta_L

Just add these lines to your .xmodmaprc, and add the line:

xmodmap $HOME/.xmodmaprc

to your .xinitrc file as the first command.
