This goes back to structured vs unstructured from elsewhere in the thread. Applying most of the editing tools is unstructured, but navigating the UI is structured.

As a result, I'm very fast at navigating menus and switching tools in my program of choice (GIMP), because those are rapid keypresses rather than forced mouse clicks. It's just so much faster to click Alt+I > S, type a few numbers, hit Tab a couple times, and enter (well, Space usually), than it is to navigate with the mouse to the Scale Image drop-down, put my hands back on the keys to type numbers in, and then switch back to the mouse to hit OK. Ctrl+Q is much easier and faster than clicking the Selection Editor button. Alt+L > T > 9 is the quickest and simplest way of rotating the current layer - a more mouse-based UI might even refuse to give me a 90-degree option and instead force me into manual control. And of course, keeping a hand on the keyboard so it can quickly type a key or shift-key is much faster and more accurate than having to mouse over to the Toolbox to select a tool.

You really need to learn how to use a tablet.

Or a 2-in-1 device with a touchscreen and a pen (e.g. Surface).

The non-graphical tablets with pens are really a different type of interaction, and one that supersedes keyboard + mouse for light graphics. Using one hand with the pen for pointer input + another hand for touch input is really powerful. Moving around, zooming, or rotating things on the screen is easier done with a hand. And a wheel menu (context or otherwise) really starts to shine with a pen.

I wish more software actually supported this. I currently own such a device (a Dell), and I'm searching for software that can utilize touch+pen input to full extent, but there aren't many programs that can.
