An old-schooler would be the one asking, "why do I need a mouse?" Anyway, it sounds like you're asking, "Why are keyboard shortcuts faster than moving a mouse to a location and then clicking [and potentially having to move to another location, such as the menu that just dropped down, and clicking again]?" Does this really need an answer?

You forgot even more inefficiency: Lifting your hand off the keyboard and moving it to the mouse, [insert your above steps], then moving back to the home row.

  I didn't forget. I just didn't feel like enumerating what I think are obvious and commonly accepted facts :). It really comes down to thought->muscle memory of keyboard shortcuts, especially those which don't require moving hands away from the home keys, vs the activity of reaching over, taking the mouse, driving it to a certain location on the screen, and then clicking. It should be obvious which will be faster.

  Is scrolling through source code really faster line by line?

    That's what you do with a mouse though. With a keyboard, you can move by semantic units (like a paragraph or function), use fuzzy search to jump to a specific function, etc.

    There are so many keyboard options for moving through source which you don't have with a mouse... - Page up/down (and especially with home row shortcuts like in Emacs and Vi) - Brace match jumps - n line jumps up or down in Vim - top/mid/bottom of view jumps - page shifts up and down without moving the cursor - top/bottom of file jumps - jump directly to a line in a file ... and more Seriously, put an Emacs or Vi power user next to a guy with an IDE and a mouse, and it's no contest.

    As a vim user, I don't really find myself needing to scroll "fast" ever. Instead, there are three common cases: 1) I'm reading through code, and scrolling one line at a time with j/k is fast enough. 2) I'm looking for a specific point in the code, in which case I use search to get to it. 3) I want to go to the bottom or the top of the file, in which case G/gg are much faster than scrolling. Sometimes I might use Page up/page down to skim a file, but that's relatively rare.

      Actually, this is also a point worth stressing for people without Vim-experience: Searching is a "first-class citizen" (as the FP-guys put it with functions). It's only ever one to two keystrokes away. You press '/', enter your phrase, and press ENTER. Stepping is done with 'n' and 'N'. There really are no convoluted hotkeys for this - which means that you do it much more liberally once you're accustomed to it. Also there's '*' and '#' to quickly find the next/previous positions of the word your cursor is currentl located on. The same thing applies there.

  No problem at all if you use a TrackPoint. I don't even have a mouse, I use the ThinkPad USB keyboard at work which includes a TrackPoint. I know some people dislike them with a passion, and they don't look fashionable, but I can't use a keyboard without one any more.
