I highly recommend everyone learn the readline keys. They apply everywhere, in chrome, messengers, etc. They're the most valuable hotkeys that I've learned other than learning vim.

I set them as the Message Of The Day in my .zshrc (or .bashrc if you don't use zsh) until I memorized them. <c-f> is genric formatting for hotkeys, where c stands for control and you type "f" at same time.

IMPORTANT: For these to be level extremely effective you MUST REMAP your caps lock key to a control key. System Prefs > Keyboard > Modifier Keys button at bottom right

    # MOTD
    function echo_color() {
      local color="$1"
      printf "${color}$2\033[0m\n"
    }
    echo_color "\033[0;90m" "c-f  Move forward"
    echo_color "\033[0;90m" "c-b  Move backward"
    echo_color "\033[0;90m" "c-p  Move up"
    echo_color "\033[0;90m" "c-n  Move down"
    echo_color "\033[0;90m" "c-a  Jump to beginning of line"
    echo_color "\033[0;90m" "c-e  Jump to end of line"
    echo_color "\033[0;90m" "c-d  Delete forward"
    echo_color "\033[0;90m" "c-h  Delete backward"
    echo_color "\033[0;90m" "c-k  Delete forward to end of line"
    echo_color "\033[0;90m" "c-u  Delete entire line"

Imagine you want to go up 2 lines to edit a HN comment. You could move your right hand to arrow key, or you can simply press caps with your pinky and type "p" with your other pinky. So much faster! Now you can see why these are so effective, and are really my favorite.

Note that as you start to use these you will be pleased to see they apply in a lot of applications. For example, type command+L in chrome to jump to the address bar and highlight it, now type "news" in the address bar. The autocomplete dropdown will pop up. Now type control+n (readline move down) and you can scroll through the list.

I'm obsessed with optimizations and efficiency and the 2 things mentioned above are the absolute gems. Also, I highly recommend: https://medium.com/vunamhung/set-a-blazingly-fast-keyboard-r...

`0` is a little to fast for me so I prefer speed `1` and it's perfect.

"c-u" only works in the terminal.
