Commands For Manipulating The History
-------------------------------------

`accept-line (Newline, Return)'
     Accept the line regardless of where the cursor is.  If this line is
     non-empty, add it to the history list.  If this line was a history
     line, then restore the history line to its original state.

`previous-history (C-p)'
     Move `up' through the history list.

`next-history (C-n)'
     Move `down' through the history list.

`beginning-of-history (M-<)'
     Move to the first line in the history.

`end-of-history (M->)'
     Move to the end of the input history, i.e., the line you are
     entering.

`reverse-search-history (C-r)'
     Search backward starting at the current line and moving `up'
     through the history as necessary.  This is an incremental search.

`forward-search-history (C-s)'
     Search forward starting at the current line and moving `down'
     through the the history as necessary.  This is an incremental
     search.

`non-incremental-reverse-search-history (M-p)'
     Search backward starting at the current line and moving `up'
     through the history as necessary using a non-incremental search
     for a string supplied by the user.

`non-incremental-forward-search-history (M-n)'
     Search forward starting at the current line and moving `down'
     through the the history as necessary using a non-incremental search
     for a string supplied by the user.

`history-search-forward ()'
     Search forward through the history for the string of characters
     between the start of the current line and the current cursor
     position (the `point').  This is a non-incremental search.  By
     default, this command is unbound.

`history-search-backward ()'
     Search backward through the history for the string of characters
     between the start of the current line and the point.  This is a
     non-incremental search.  By default, this command is unbound.

`yank-nth-arg (M-C-y)'
     Insert the first argument to the previous command (usually the
     second word on the previous line).  With an argument N, insert the
     Nth word from the previous command (the words in the previous
     command begin with word 0).  A negative argument inserts the Nth
     word from the end of the previous command.

`yank-last-arg (M-., M-_)'
     Insert last argument to the previous command (the last word of the
     previous history entry).  With an argument, behave exactly like
     `yank-nth-arg'.
