You can only do this if -the prior command is @key{C-y} or @key{M-y}. -@end table - -When you use a kill command, the text is saved in a @dfn{kill-ring}. -Any number of consecutive kills save all of the killed text together, so -that when you yank it back, you get it in one clean sweep. The kill -ring is not line specific; the text that you killed on a previously -typed line is available to be yanked back later, when you are typing -another line. - -@node Readline Arguments, , Readline Killing Commands, Readline Interaction -@subsection Readline Arguments - -You can pass numeric arguments to Readline commands. Sometimes the -argument acts as a repeat count, other times it is the @i{sign} of the -argument that is significant. If you pass a negative argument to a -command which normally acts in a forward direction, that command will -act in a backward direction. For example, to kill text back to the -start of the line, you might type @key{M--} @key{C-k}. - -The general way to pass numeric arguments to a command is to type meta -digits before the command. If the first `digit' you type is a minus -sign (@key{-}), then the sign of the argument will be negative. Once -you have typed one meta digit to get the argument started, you can type -the remainder of the digits, and then the command. For example, to give -the @key{C-d} command an argument of 10, you could type @key{M-1 0 C-d}. - - -@node Readline Init File, , Readline Interaction, Readline Top -@section Readline Init File - -Although the Readline library comes with a set of Emacs-like -keybindings, it is possible that you would like to use a different set -of keybindings.

The type declaration for `Function' is: - -@code{typedef int Function ();} - -The reason for declaring this new type is to make it easier to discuss -pointers to C functions.

Instead of the classic C declaration - -@code{int (*)()func;} - -we have - -@code{Function *func;} - -@node Function Naming, Keymaps, The Function Type, Custom Functions -@subsection Naming a Function - -The user can dynamically change the bindings of keys while using -Readline. This is done by representing the function with a descriptive -name. The user is able to type the descriptive name when referring to -the function. Thus, in an init file, one might find - -@example -Meta-Rubout: backward-kill-word -@end example - -This binds @key{Meta-Rubout} to the function @emph{descriptively} named -@code{backward-kill-word}. You, as a programmer, should bind the -functions you write to descriptive names as well.
