Going to the end/beginning of the line depending which place it’s closer to the point you want to edit, and then moving your cursor over one character at a time to get to the destination - sounds familiar? I was so frustrated with that, that I made it a habit to enter all the commands in text editor then copy & paste to the terminal window!"
