#### 31.4.8 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-uppercase-version (M-a, M-b, M-`x`, ...)`
  If the metafied character x is lowercase, run the command that is bound to the corresponding uppercase character.
`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.
`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.
