Reusing previous command argument in new command

Let’s say that you’ve just created a new directory with mkdir awesome. As you don’t use zsh which comes with a handy take command (after creating a directory jumps to it afterwards), you have to use cd. Fortunately there’s no need to re-type the name of the directory. Type cd and press <kbd>Alt .</kbd>. This way you can reuse previous arguments and save a few key strokes.
