GNU Info (emacs-lisp-intro.info)Kill Ring OverviewKill Ring Overview ================== The kill ring is a list of textual strings. This is what it looks like: ("some text" "a different piece of text" "yet more text") If this were the contents of my kill ring and I pressed `C-y', the string of characters saying `some text' would be inserted in this buffer where my cursor is located. The `yank' command is also used for duplicating text by copying it. The copied text is not cut from the buffer, but a copy of it is put on the kill ring and is inserted by yanking it back. Three functions are used for bringing text back from the kill ring: `yank', which is usually bound to `C-y'; `yank-pop', which is usually bound to `M-y'; and `rotate-yank-pointer', which is used by the two other functions. These functions refer to the kill ring through a variable called the `kill-ring-yank-pointer'. Indeed, the insertion code for both the `yank' and `yank-pop' functions is: (insert (car kill-ring-yank-pointer)) To begin to understand how `yank' and `yank-pop' work, it is first necessary to look at the `kill-ring-yank-pointer' variable and the `rotate-yank-pointer' function. automatically generated by info2www version 1.2.2.9 |
