Miscellaneous Commands (Debugging with GDB)

32.4.8 Some Miscellaneous Commands

re-read-init-file (C-x C-r): Read in the contents of the inputrc file, and incorporate any bindings or variable assignments found there.
abort (C-g): Abort the current editing command and ring the terminal’s bell (subject to the setting of bell-style).
do-lowercase-version (M-A, M-B, M-x, …): If the metafied character x is upper case, run the command that is bound to the corresponding metafied lower case character. The behavior is undefined if x is already lower case.
prefix-meta (ESC): Metafy the next character typed. This is for keyboards without a meta key. Typing ‘ESC f’ is equivalent to typing M-f.
undo (C-_ or C-x C-u): Incremental undo, separately remembered for each line.
revert-line (M-r): Undo all changes made to this line. This is like executing the undo command enough times to get back to the beginning.
tilde-expand (M-~): Perform tilde expansion on the current word.
set-mark (C-@): Set the mark to the point. If a numeric argument is supplied, the mark is set to that position.
exchange-point-and-mark (C-x C-x): Swap the point with the mark. The current cursor position is set to the saved position, and the old cursor position is saved as the mark.
character-search (C-]): A character is read and point is moved to the next occurrence of that character. A negative count searches for previous occurrences.
character-search-backward (M-C-]): A character is read and point is moved to the previous occurrence of that character. A negative count searches for subsequent occurrences.
skip-csi-sequence (): Read enough characters to consume a multi-key sequence such as those defined for keys like Home and End. Such sequences begin with a Control Sequence Indicator (CSI), usually ESC-[. If this sequence is bound to "\e[", keys producing such sequences will have no effect unless explicitly bound to a readline command, instead of inserting stray characters into the editing buffer. This is unbound by default, but usually bound to ESC-[.
insert-comment (M-#): Without a numeric argument, the value of the comment-begin variable is inserted at the beginning of the current line. If a numeric argument is supplied, this command acts as a toggle: if the characters at the beginning of the line do not match the value of comment-begin, the value is inserted, otherwise the characters in comment-begin are deleted from the beginning of the line. In either case, the line is accepted as if a newline had been typed.
dump-functions (): Print all of the functions and their key bindings to the Readline output stream. If a numeric argument is supplied, the output is formatted in such a way that it can be made part of an inputrc file. This command is unbound by default.
dump-variables (): Print all of the settable variables and their values to the Readline output stream. If a numeric argument is supplied, the output is formatted in such a way that it can be made part of an inputrc file. This command is unbound by default.
dump-macros (): Print all of the Readline key sequences bound to macros and the strings they output. If a numeric argument is supplied, the output is formatted in such a way that it can be made part of an inputrc file. This command is unbound by default.
emacs-editing-mode (C-e): When in vi command mode, this causes a switch to emacs editing mode.
vi-editing-mode (M-C-j): When in emacs editing mode, this causes a switch to vi editing mode.
