Some commands that I often use in Emacs

Before the end of June, 2005. I never heard of `Emacs‘ despite graduating with a computer science degree. Thanks to Daniel who told me such an excellent Editor and who taught me lots of tricks.

Each Emacs command can be invoked by M-x. (Alt key + x) with a command name. or C-x (Ctrl + x) followed by another key combination. For example , M-x shell will open a shell window with the Emacs editor. Here are some useful shortcuts of commonly used commands for a beginner.

C-x C-c End the Emacs session.
C-x C-f Open a file.
C-x C-s Save the file.
C-g Cancel the unfinished command.
