Text editor of termux

Question

How to use Text editor of termux ?
Can we open or save any file from there ?

Answer 1

First install man using
pkg install man

Then go here - https://wiki.termux.com/wiki/Text_Editors
Choose any one of the text editors. I recommend "nano" if you are low on space (occupies a few MBs of space), "emacs" if you have no shortage of space (occupies about 100-200MB), or my personal favourite - Vim (occupies about 30MB of space).
Install the chosen text editor using the instructions. Then do:
man <the-editor-you-chose>

It will show on the screen a full manual of the text editor. Or you can even go on the internet to see how to work with those editors.

Command line text editors can be hard to work with at first because you need to use key bindings instead of mouse, and on a phone it is even harder because the keyboard on a phone does not a have lot of keys that a normal keyboard has. For that, I recommend an app called "Hacker's Keyboard" because with it you have access to keys of a normal keyboard.
