Registers
Emacs registers are compartments where you can save text,
rectangles, positions, and other things for later use. Once you save
text or a rectangle in a register, you can copy it into the buffer
once, or many times; you can move point to a position saved in a
register once, or many times.
Each register has a name, which consists of a single character.
A register can
store a piece of text, a rectangle, a position, a window configuration,
or a file name, but only one thing at any given time. Whatever you
store in a register remains there until you store something else in that
register. To see what a register r contains, use M-x
view-register.
- M-x view-register <RET> r
- Display a description of what register r contains.
- Position: Saving positions in registers.
- Text: Saving text in registers.
- Rectangle: Saving rectangles in registers.
- Configurations: Saving window configurations in registers.
- Files: File names in registers.
- Numbers: Numbers in registers.
- Bookmarks: Bookmarks are like registers, but persistent.
