  • deleted things cannot be reinserted in this way, but you can undo a deletion

Reinsertion of killed text is called "yanking".


Keyboard shortcuts Effects
C-/ undo a change to text(C-/ 不会撤销光标移动命令,滑动命令)

Normally, C-/ undoes the changes made by one command; if you repeat C-/ several times in a row, each repetition undoes one more command.
