GNU Info (elisp)Input ModesInput Modes ----------- - Function: set-input-mode interrupt flow meta quit-char This function sets the mode for reading keyboard input. If INTERRUPT is non-null, then Emacs uses input interrupts. If it is `nil', then it uses CBREAK mode. The default setting is system-dependent. Some systems always use CBREAK mode regardless of what is specified. When Emacs communicates directly with X, it ignores this argument and uses interrupts if that is the way it knows how to communicate. If FLOW is non-`nil', then Emacs uses XON/XOFF (`C-q', `C-s') flow control for output to the terminal. This has no effect except in CBREAK mode. Note: Flow Control. The argument META controls support for input character codes above 127. If META is `t', Emacs converts characters with the 8th bit set into Meta characters. If META is `nil', Emacs disregards the 8th bit; this is necessary when the terminal uses it as a parity bit. If META is neither `t' nor `nil', Emacs uses all 8 bits of input unchanged. This is good for terminals that use 8-bit character sets. If QUIT-CHAR is non-`nil', it specifies the character to use for quitting. Normally this character is `C-g'. Note: Quitting. The `current-input-mode' function returns the input mode settings Emacs is currently using. - Function: current-input-mode This function returns the current mode for reading keyboard input. It returns a list, corresponding to the arguments of `set-input-mode', of the form `(INTERRUPT FLOW META QUIT)' in which: INTERRUPT is non-`nil' when Emacs is using interrupt-driven input. If `nil', Emacs is using CBREAK mode. FLOW is non-`nil' if Emacs uses XON/XOFF (`C-q', `C-s') flow control for output to the terminal. This value is meaningful only when INTERRUPT is `nil'. META is `t' if Emacs treats the eighth bit of input characters as the meta bit; `nil' means Emacs clears the eighth bit of every input character; any other value means Emacs uses all eight bits as the basic character code. QUIT is the character Emacs currently uses for quitting, usually `C-g'. automatically generated by info2www version 1.2.2.9 |
