The keyboard bindings for <ALT> in urxvt depend on the URxvt.meta8
resource. If URxvt.meta8 is false (which is the default), <ALT><key>
sends <ESC><key> and thus you need to write your maps for <ESC>mumble:

nnoremap <Esc>j "zdd"zp
nnoremap <Esc>k k"zdd"zpk

If URxvt.meta8 is true, <ALT><key> sends an 8-bit character and sens
the Meta flag, which means you have to write your maps for <M-mumble>:

nnoremap <M-j> "zdd"zp
nnoremap <M-k> k"zdd"zpk

In order to change the URxvt.meta8 resource, either add

*URxvt.meta8: true

to /etc/X11/app-defaults/URxvt (the path may differ on your machine), or
add

URxvt.meta8: true

to ~/.Xresources (and run "xrdb -merge ~/.Xresources" for it to take
effect immediatley).

The xterm equivalent of URxvt.meta8 is VT100.metaSendsEscape.
