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; once you save a position in a register, you can jump back to that position once, or many times.
Hello. And Bye.
== Naming convention ==
There are 62 registers, each with a single character for a name:
* from a to z
* from A to Z, different from a to z
* from 0 to 9
== Functions ==
A register can store a position, a piece of text, a rectangle, a number, 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.
