Emacs is an editor used by many, on the Linux and Unix Operating system.
Mainly used by programmers and developers, it has a lot to offer.
However, If you are interested in quick text processing, VIM might serve the purpose better.
Following is the list of most commonly used shortcuts in emcas:-
Before we begin, it is important to point out that "ctrl" and "meta" are the two most used keys in emacs.
1) Ctrl: we are aware of and is available on most keyboards.
2) Meta: But what is meta ? It's key often found on macbooks and they are not explicitly available in most of the laptops and desktop keyboards. But, the "left-alt" or the "right-alt" key will serve as meta key(by default) in such cases. If, this is not the case, stuff such as "auto hot key" programs.
So, here we begin the list of commands:-
