There's no way that's going to be as fast. It's also going to be a lot more tiring, if you do that a lot, than merely moving your fingers.
Some things are quicker to do with the mouse and some things are quicker to do using keyboard shortcuts. I don't understand why people take such absolutist positions on this.
My arm doesn't get tired from moving a few inches to grab the mouse.
Compared to a veteran vim/emacs user, you'd to do a whole ton of mouse movements to get the same effect of a few keystrokes.
"Some things are quicker to do with the mouse and some things are quicker to do using keyboard shortcuts."
The only things I've found to be quicker to do with the mouse are doing things like drawing in Photoshop/GIMP/Inkscape, or interacting with GUI applications which don't have keyboard shortcuts for most of their functions. Text editing and coding, on the other hand, tends to be much faster, sometimes exponentially faster, than the mouse.
Depends on what you're doing. Again with the absolutism!
Do you type with just one hand? Because that's what you'd need to do to replicate that performance while coding.
If you type with both hands, now you have to add in the time it takes you to move one hand from the keyboard to the mouse, make the mouse motion (which could be far across the screen) and then back to the keyboard, repeating that cycle for every single operation which involves the mouse.
Meanwhile, someone who knows vim well and is not reliant on the mouse can type with both hands and only has to move their fingers.
