Well, they both can work. It depends on which one you want to learn about. But
with the doc webpages down, xmodmap is probably easier.

OK, so you need to use Mode_shift with this "old style" keymap.

It's defined in symbols/level3, but you don't want that right now.

With xev, which you've done below.

Well, the modifier that it sees is Alt_L. You want it to see Mode_shift. You
can cause this to happen by putting this into your .Xmodmap file:
keysym Alt_L = Mode_switch
Then run `xmodmap .Xmodmap` and the left alt key should generate Mode_switch
and you can get your characters.
