’ runs the command self-insert-command (found in global-map), which is an interactive built-in function in ‘C source code’.
It is bound to many ordinary text characters.
Insert the character you type. Whichever character you type to run this command is inserted. The numeric prefix argument N says how many times to repeat the insertion. Before insertion, ‘expand-abbrev’ is executed if the inserted character does not have word syntax and the previous character in the buffer does. After insertion, ‘internal-auto-fill’ is called if ‘auto-fill-function’ is non-nil and if the ‘auto-fill-chars’ table has a non-nil value for the inserted character. At the end, it runs ‘post-self-insert-hook’.
