Currently the output of /key is like:

    meta-wmeta-meta2-B => /window down

which confused me at first, as I read it as: press meta + wmeta + meta2-B simultaneously, so I looked for a wmeta key, which doesn't exist (though I thought it might stand for the cmd key).


If it had said:

    meta-w, meta-meta2-B => /window down

or:

    meta+w, meta+meta2-B => /window down

it would've been clear to me to press meta+w, followed by meta + the down key.
Maybe it is possible to add this by applying some regular expression replace on the output with something like:

    s/([a-Z])(meta|ctrl)/\1, \2/
