The separator can separates the input into two halves. One half will be displayed on screen and the other half will be printed to stdout.
the dmenu in X has the patch 'separator' that make dmenu looks well,
$echo "alpha beta charlie" | dmenu -d ' '
the -d ' ' means separated by a space, "alpha" will be displayed, and "beta charlie" will be printed to stdout upon selection.
Would bemenu can add that?
