I really think basic text navigation is no longer a problem since the the adoption of PC keyboards in the 1980s and 1990s. Key arrows are easy to find blindly except maybe on some screwed up laptop designs.
Not trying to start a vim-vs-whatever war here, though I suppose that's inevitable in a discussion of tabs-vs-spaces...
I deeply appreciate the automation vim & co. offer, but many people, like me, simply have no interest in climbing up the learning curve for editors.
I struggle with trying to get others to change their files because a particular program I like and use a lot handles their file a certain way. This reminds me of the olden days of the old Microsoft way where the solution seemed to be around making every app respond in the way way so it was possible to guarantee what arrow does across all apps.
But that way lost and now files are used in all sorts of weird wonderful ways.
