> Gratuitous distractions from the keyboard only slow down the experienced user. This is true even for GUIs. I used to maintain an accounting software. Everything could be done just with the keyboard. You could use the mouse, but it was optional. People were registering hundreds of invoices a day. That will not be possible if they need to take their hands out of the keyboard, go to the mouse, move it and go back to the keyboard. Web UIs are extremely inefficient. But it is not a big deal as they are designed more for leisure than for the professional. Hacker News or Reddit interface is good enough to write a message like this one. I would like to see which interface use professional Reddit posters. From Russian trolls to /r/hailcorporate professionals need an interface that is not so mouse dependent. The command line it is also a GUI, mine at least allows me to use the mouse to copy/paste text. But it is an optional feature that I don't need to use each time I write a command.
