Keyboard shortcuts faster? Afraid not for mortals
Only if you are familiar with them and it takes people months to learn them. Most (including me) can't be bothered.
I grew up using MSDOS and writing batch files, but I avoid the CLI in Ubuntu (too * complicated unless I can cut and paste from a guide or it's one of the few things I know does what I want e.g. sudo gedit when I dare hack a config file)
