The Just in that sentence is wholly unjustified. There are plenty of cli/tui/console/shell shortcuts that are incredibly useful, yet they are wholly undiscoverable and do not work cross-platform, e.g. shell motions between macOS and reasonable OSes.
All the movement commands I know work the same in the terminal on a default install of macOS as it does in the terminal on various Linux distros I use.
Ctrl+A to go to beginning of line
Ctrl+E to go to end of line
Esc, B to jump cursor one word backwards
Esc, F to jump cursor one word forward
Ctrl+W to delete backwards until beginning of word
And so on
Both in current versions of macOS where zsh is the default shell, and in older versions of macOS where bash was the default shell.
Am I misunderstanding what you are referring to by shell motions?
Yea, but ctrl + arrows to move cursor between ‘words’ don’t work, especially sad when SSH’ing in from linux. It works fine when using terminal on macOS - you just use command + arrows.
