I launch favourite commands with 2 clicks. Once on the App launcher button, and once on the App itself. My hand is on the mouse anyway. So it’s fast. Way faster than typing a whole bunch of characters. For less used apps It’s 3 clicks as I’d open a category like “Media” or “Games”. And doing that, I get to see what I have in there. This builds up a picture in the users head for future use. Learning “Add to favourites” is time well spent. It can even be called “Pin to Start” or “Bookmark on Launcher” it doesn’t matter. You don’t need to memorise that exactly like the CLI. And right-clicking things is already second nature to huge numbers of users.
So I have no incentive to use text commands. It’s not faster. My hand is on the mouse for my apps anyway. And the CLI has terrible usability, via poor learnability, zero tolerance, and poor visual feedback. And completely useless for most things I do, like working with 3D models, images or drawings. I’m not a “text-worker” like IT tend to be. Plus, I want more non-IT people to use Linux, so discovering the easy ways to do things can help spread the word to them.
For me it would be like stepping off a high-speed train and walking over uneven ground instead.
