12.11.1 Marking the region

First of all, you need to mark a region of text in the current buffer which you want to transfer into the kill ring. There are two ways that you can do this:

The selected text is highlighted using the Region Highlight text style.

To mark the region with the keyboard, place the cursor at the beginning of the text you want to mark, press Ctrl+Space , and move the cursor to the end of the region you want to mark, using keyboard commands to do so . Unlike marking with the mouse, this does not highlight the region.

Because the Editor does not highlight the marked region when you use keyboard commands, a useful EMACS key to remember is Ctrl+X Ctrl+X . Pressing this exchanges the current cursor position with the start of the marked region and highlights the region. Press Ctrl+X Ctrl+X a second time to return the cursor to its original position and leave the region marked.

Press Ctrl+G (or Esc in MS Windows emulation) to remove the highlighting in a region.
