This is a terse description of the new features added to readline-6.1 since the release of readline-6.0. 1. New Features in Readline a. New bindable function: menu-complete-backward. b. In the vi insertion keymap, C-n is now bound to menu-complete by default, and C-p to menu-complete-backward. c. When in vi command mode, repeatedly hitting ESC now does nothing, even when ESC introduces a bound key sequence. This is closer to how historical vi behaves. d. New bindable function: skip-csi-sequence. Can be used as a default to consume key sequences generated by keys like Home and End without having to bind all keys. e. New application-settable function: rl_filename_rewrite_hook. Can be used to rewite or modify filenames read from the file system before they are compared to the word to be completed. f. New bindable variable: skip-completed-text, active when completing in the middle of a word. If enabled, it means that characters in the completion that match characters in the remainder of the word are "skipped" rather than inserted into the line. g. The pre-readline-6.0 version of menu completion is available as "old-menu-complete" for users who do not like the readline-6.0 version. h. New bindable variable: echo-control-characters. If enabled, and the tty ECHOCTL bit is set, controls the echoing of characters corresponding to keyboard-generated signals. i. New bindable variable: enable-meta-key. Controls whether or not readline sends the smm/rmm sequences if the terminal indicates it has a meta key that enables eight-bit characters.
