If you have the Dock set to automatically hide, then you may not like the default amount of time it takes for the Dock to appear, and the speed of the animation. You can customize these by using the Terminal to change two hidden macOS preferences. You can delay the appearance of the Dock so that you can access other items at the bottom of your screen. You can also speed up or eliminate the animation if you find it is too slow for you.
To my way of thinking, I wish the Dock would leave my Mac and never come back. Using Spotlight, Alfred, or Launchpad are more than adequate for my accessing of apps. I wonder what the upper limit for that delay number might be?
Using the Dock on the left side is more helpful rather than tediously mousing down to find the dock continuously. The screen is wider that tall and any screen shots show up on the right side so they are not covered.
I want to thank you very much for this tutorial. I use Autohide but I always wanted to customize the speed of its appearance. Now, I was able to set it just right for me.
BTW...Thank you for all your tutorials!!! They're all wonderful.
