| # With this in place, you should rarely need "zle -N self-insert frob"

 | |
| # 	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
