This is software with a learning curve. It's set up so that you can learn it and then be very productive. From the number of Linux CLI people on here, you'll find a lot of people who are sympathetic to that.
If you want a friendly UI there's always SketchUp.
Addendum having just looked at the blender "hotkey chart" you linked: That's not a hotkey chart. That's a detailed description of every command with a hotkey.
If you added similar descriptions in the AutoCAD commands list it could probably hit 100 pages.
Besides, if your finger memory hasn't picked up all of blender yet, tap spacebar for command search. As long as you remember vaguely what something's called you'll find it in there.
