9870 | The sequence is sufficient to specify a non-prefix command in the | |
9871 | current local and global maps. | |
9872 | ||
9873 | First arg PROMPT is a prompt string. If nil, do not prompt specially. | |
9874 | Second (optional) arg CONTINUE-ECHO, if non-nil, means this key echos | |
9875 | as a continuation of the previous key. | |
9876 | ||
9877 | The third (optional) arg DONT-DOWNCASE-LAST, if non-nil, means do not | |
9878 | convert the last event to lower case. (Normally any upper case event | |
9879 | is converted to lower case if the original event is undefined and the lower | |
9880 | case equivalent is defined.) A non-nil value is appropriate for reading | |
9881 | a key sequence to be defined. | |
9882 | ||
9883 | A C-g typed while in this function is treated like any other character, | |
9884 | and `quit-flag' is not set. | |
9885 | ||
9886 | If the key sequence starts with a mouse click, then the sequence is read | |
9887 | using the keymaps of the buffer of the window clicked in, not the buffer | |
9888 | of the selected window as normal. | |
9889 | ||
9890 | `read-key-sequence' drops unbound button-down events, since you normally | |
9891 | only care about the click or drag events which follow them. If a drag | |
9892 | or multi-click event is unbound, but the corresponding click event would | |
9893 | be bound, `read-key-sequence' turns the event into a click event at the | |
9894 | drag's starting position. This means that you don't have to distinguish | |
9895 | between click and drag, double, or triple events unless you want to. | |
9896 | ||
9897 | `read-key-sequence' prefixes mouse events on mode lines, the vertical | |
9898 | lines separating windows, and scroll bars with imaginary keys | |
9899 | `mode-line', `vertical-line', and `vertical-scroll-bar'. | |
9900 | ||
9901 | Optional fourth argument CAN-RETURN-SWITCH-FRAME non-nil means that this | |
9902 | function will process a switch-frame event if the user switches frames | |
9903 | before typing anything. If the user switches frames in the middle of a | |
9904 | key sequence, or at the start of the sequence but CAN-RETURN-SWITCH-FRAME | |
9905 | is nil, then the event will be put off until after the current key sequence. | |
9906 | ||
9907 | `read-key-sequence' checks `function-key-map' for function key | |
9908 | sequences, where they wouldn't conflict with ordinary bindings. See | |
9909 | `function-key-map' for more details. | |
9910 | ||
9911 | The optional fifth argument COMMAND-LOOP, if non-nil, means | |
9912 | that this key sequence is being read by something that will | |
9913 | read commands one after another. It should be nil if the caller | |
9914 | will read just one key sequence. */) | |
