10.5 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 reg

Store number into register reg (number-to-register).

C-u number C-x r + reg

Increment the number in register reg by number (increment-register).

C-x r g reg

Insert the number from register reg into the buffer.

C-x r g is the same command used to insert any other sort of register contents into the buffer.
