How to enable history completion in command line?

How to enable history completion in command line?

[Han Pingtian]

Hello,

How can I enable history completion in the command line? That's typing
a command then hit some key to let zsh completes the whole command 
line based on history.

Thanks in advance.

Looking at
http://zsh.sourceforge.net/Doc/Release/Zsh-Line-Editor.html#History-Controlmy
educated guess would be to bind history-beginning-search-backward to
something

Are you sure you're not looking for history-beginning-search-backward?

Completion is extremely word-oriented, so using it to retrieve anything
that has whitespace and other syntactic separators is difficult.  There
are tricks you can do with "compadd -Q -U" to cause multi-word strings
to be inserted onto the command line, but attempting to do any sort of
menu completion (with limited exceptions for menu selection) will fail
because completion will begin to limit itself to the single word nearest
the cursor as soon as the first replacement is done.

Thanks, Bart and Karoly.

history-beginning-search-backward works just fine. I was just curious to the 
feature about '_history_complete_word' discussed in previous letter. Now
it looks like it will show a menu to the user for selection. This isn't
really useful I think. I'm going to bind up-arrow and down-arrow  to
'history-beginning-search-backward' and 'history-beginning-search-forward'
respectively.
