_nambiar has a short video on how painful it is to watch people use other editors and reach for the mouse every time they want to do some navigation or select text. He’s an Emacs user but his message will resonate with Vim users as well.
The video is definitely propaganda and certainly a fit subject for Red Meat Friday but no matter how much the naysayers try to deny it, it contains a nugget of truth. Some of the naysayers on the original reddit post make the ludicrous argument that his argument fails because some of his key bindings are long. Even leaving aside the fact that the first thing _nambiar says in the video is that you should learn to touch type, every Emacs user knows that you can rebind the bindings you use a lot to whatever you like.
There is, of course, a long standing argument about whether using the mouse or the keyboard for navigation is faster and some research claims that the mouse is faster but I’d be willing to bet that the editor used in those studies wasn’t Emacs. If you’re using some brain dead editor that makes you use the arrow keys to move around, then yes, the mouse may be faster but if you’re using an editor with robust keyboard navigation like Emacs or Vim, then I doubt a mouse could compete.
In any event, if you’re an Emacs or Vim user, enjoy the red meat.
Update : The “research” claims that the mouse not the keyboard is faster.
