Current File : //proc/2/root/proc/2/cwd/usr/local/ssl/share/zsh/4.3.11/functions/history-beginning-search-menu
# Menu-driven alternative to history-beginning-search-backward.
# As it uses a menu there is no sense of "forward" or "backward", however;
# the entire history is searched.
#
# Configuration:
#   autoload -Uz history-beginning-search-menu
#   zle -N history-beginning-search-menu
#   bindkey '\eP' history-beginning-search-menu
#
# Example:
#   % /bin/su<ESC-P>
#   Enter digit:
#   1 /bin/su -c 'make install'            4 /bin/su - perforce
#   2 /bin/su                              5 /bin/su -c
#   3 /bin/su -c 'chown pws:pws **/*(u0)'
#
# Typing "1" expands the line to
#   % /bin/su -c 'make install'
#
# With a prefix argument, the search is not anchored to the beginning,
# so for example "/su" could expand to "p4 files //depot/support/..."
#
# If this is bound to a widget containing "-end", e.g.
#   zle -N history-beginning-search-menu-end history-beginning-search-menu
# then the cursor is put at the end of the line, else it is left
# after the matched characters.
#
# If this is bound to a widget containing "-space", then any space in
# the line so far is matched as a wildcard.  (This means putting a space
# at the start of the line is equivalent to specifying a prefix
# argument.)
