Editing with Version Control

These are the commands for editing a file maintained with version control:

C-x C-q

C-x v v

Check the visited file in or out.

C-x v u

Revert the buffer and the file to the last checked in version.

C-x v c

Remove the last-entered change from the master for the visited file. This undoes your last check-in.

C-x v i

Register the visited file for version control.

(C-x v is the prefix key for version control commands; all of these commands except for C-x C-q start with C-x v.)
