# With this in place, you should rarely need "zle -N self-insert frob"
# again. Instead you do this:
#
# bindkey -N frobber main
# zle -N frobber+self-insert frob
#
# Then, whenever you wish to replace self-insert with frob, change
# keymaps:
#
# zle recursive-edit -K frobber
# Here's a simple example, which improves upon the caps-lock example in
# the zsh manual entry for recursive-edit:
#
# ucase+self-insert() {
# LBUFFER+=${(U)KEYS[-1]}
# }
# zle -N ucase+self-insert
# caps-lock() {
# bindkey -N ucase $KEYMAP
# bindkey -M ucase "$KEYS" .accept-line
# zle recursive-edit -K ucase || zle send-break
# }
# zle -N caps-lock
#
# To turn this on, pick a key sequence (I've chosen ctrl-x shift-L) and
# bind the caps-lock widget to it:
#
# bindkey -M main '^XL' caps-lock
# Another example of using a continuation widget to propagate accept-line
# (or any other binding from the original keymap) through the caller:
#
# bindkey -N newkeymap $KEYMAP
# recursive-edit-and-accept() {
# local -a __accepted
# zle -N newkeymap+accept-line end-recursive-edit
# zle recursive-edit -K newkeymap || zle send-break
# if [[ ${__accepted[0]} != end-recursive-edit ]]
# then zle "${__accepted[@]}"; return
# else return 0
# fi
# }
# end-recursive-edit() {
# __accepted=($WIDGET ${=NUMERIC:+-n $NUMERIC} "$@")
# zle .accept-line
# return 0
# }
