I was using jEdit. And once willing to change to, so called modern text editor, Atom Text Editor. Then I did some comparisons among the text editors. At the end, now my primary text editor for coding is Emacs.
Emacs requires some time to learn and practise. But at the end, I love it too much. It is so powerful, no other text editor to compare with it. But the primary usage is for coding.
There are several modes that are interesting. I suggest to know these modes:
- dired – Directory browsing
- ibuffer – List and manage opened files
- eshell – Emacs shell, like bash
- ielm – Inferior Emacs Lisp Mode. Interactive Lisp environment
- w3m – w3m web browser, requires package installation.
- eww – Default web browser in Emacs, but I found it is difficult to use compared to w3m
Customising Emacs to fit your pattern requires some time.
Just share my .emacs file,

It would be better if you learn Emacs from the beginning and try to adapt the default key bindings (hotkeys). Because, if you replace some of the hotkeys with the ones you are used to, you may miss the default key binding power. No more Ctrl+X, C, or V for cut, copy, and paste. Just learn Emacs and customise it.
One more thing, I was looking for folding (collapse and expand) feature. But failed to find one. Yet, just use the key binding C-M-p and C-M-n are enough to fit my demand.
