How to implement text editing features in terminal interface? Sorry if the title is confusing but essentially what I want is to have standard text editor features like Command&lt; to move to the beginning of the line or CommandShiftBackspace to erase a line. Is it possible to implement such stuff in the terminal interface? Preferably, I would not download a terminal emulator like iTerm etc..
There are ways to navigate in the terminal but they don't use the macOS keystrokes for navigation as the BASH shell actually predate macOS/NeXT. For example CtrlA moves to the beginning of a line and CtrlE moves the cursor to the end of a line. A quick search online on BASH shell keyboard shortcuts will yield a whole list like this, for example.

As an alternative BBEdit is a text editor that has been around on the Mac for ever. Way Pre-OS X. And one of the features is a command line window that acts much like a text editor and uses the standard Mac keybindings. But then you'll have to buy a programmers text editor to get the features you want in a shell window.

Might be best if you just learn the BASH keybindings, as that is lots cheaper ;-)
