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 according to the state of the HISTCONTROL variable.  If the line is a modified history line, then restore the history line to its original state. previous-history (C-p) Fetch the previous command from the history list, moving back in the list. next-history (C-n) Fetch the next command from the history list, moving forward in the 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 currently being entered. 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 history as necessary.  This is an incremental search. non-incremental-reverse-search-history (M-p) Search backward through the history starting at the current line using a non-incremental search for a string supplied by the user. non-incremental-forward-search-history (M-n) Search forward through the history 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 point.  This is a non-incremental search. 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. history-substring-search-backward Search backward through the history for the string of characters between the start of the current line and the current cursor position (the point).  The search string may match anywhere in a history line.  This is a non-incremental search. history-substring-search-forward Search forward through the history for the string of characters between the start of the current line and the point.  The search string may match anywhere in a history line.  This is a non- incremental search. yank-nth-arg (M-C-y) Insert the first argument to the previous command (usually the second word on the previous line) at point.  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.  Once the argument n is computed, the argument is extracted as if the "!n" history expansion had been specified. yank-last-arg (M-., M-_) Insert the last argument to the previous command (the last word of the previous history entry).  With a numeric argument, behave exactly like yank-nth-arg.  Successive calls to yank-last-arg move back through the history list, inserting the last word (or the word specified by the argument to the first call) of each line in turn.  Any numeric argument supplied to these successive calls determines the direction to move through the history.  A negative argument switches the direction through the history (back or forward).  The history expansion facilities are used to extract the last word, as if the "!$" history expansion had been specified. shell-expand-line (M-C-e) Expand the line as the shell does.  This performs alias and history expansion as well as all of the shell word expansions. See HISTORY EXPANSION below for a description of history expansion. history-expand-line (M-^) Perform history expansion on the current line.  See HISTORY EXPANSION below for a description of history expansion. magic-space Perform history expansion on the current line and insert a space. See HISTORY EXPANSION below for a description of history expansion. alias-expand-line Perform alias expansion on the current line.  See ALIASES above for a description of alias expansion. history-and-alias-expand-line Perform history and alias expansion on the current line. insert-last-argument (M-., M-_) A synonym for yank-last-arg. operate-and-get-next (C-o) Accept the current line for execution and fetch the next line relative to the current line from the history for editing.  A numeric argument, if supplied, specifies the history entry to use instead of the current line. edit-and-execute-command (C-x C-e) Invoke an editor on the current command line, and execute the result as shell commands.  Bash attempts to invoke $VISUAL, $EDITOR, and emacs as the editor, in that order.
