18.5 Keeping Numbers in Registers
There are commands to store a number in a register, to insert
the number in the buffer in decimal, and to increment it. These commands
can be useful in keyboard macros (see Keyboard Macros).
- C-u number C-x r n r
- Store number into register r (
number-to-register
).
- C-u number C-x r + r
- Increment the number in register r by number
(
increment-register
).
- C-x r i r
- Insert the number from register r into the buffer.
C-x r i is the same command used to insert any other sort of
register contents into the buffer. C-x r + with no numeric
argument increments the register value by 1; C-x r n with no
numeric argument stores zero in the register.
