Erasing text can be handled in five ways.
Note that, the 'Esc digits' command is used in two cases only: to delete several lines and to play a macro several times (see §2.10 page ).
When deleted, text is stored in an unlimited linked kill-buffer list (each deleted text can be restored). This kill-buffer can be mapped with Display Kill Buffer in the Window menu. It is viewed as a scrolling list with the beginning of each entry. The first entry corresponds to the last remove operation. When selected, an entry is restored at the current position. The kill-buffer is shared by all buffers of a session.
