Linkbait title alert. Please, please stop this crap. Article really says: n00b vim users, consider disabling hjkl while learning other movement commands. What vim user does all their movement with hjkl only anyway? If you're going to deliberately cripple your editing habits like that, or if you're not even bother to learn other movement command at the same time as getting used to hjkl, you might as well stick to note…
>What vim user does all their movement with hjkl only anyway? Having used vim for nearly two decades now, my primary movement routine seems to be start with "/" and "?". In other words, jump to the approximate location using a word search and "W" or "w" as needed to the specific word, then use the hjkl or other commands to further refine the cursor's location.
Young programmers should be made aware that there are now programming editors that do away with the need to think of a way to trick the program into moving the cursor where you want it to go. Modern editors respond to direct, concise keyboard entries to move the editing cursor to the desired destination. Like pressing the arrow keys. Or pointing at the destination with a mouse and clicking -- things like that.
Even ubiquitous command-line editors like Pico are easier to use than vi/vim. The reason is that Pico doesn't have vim's history to contend with, and its consequent rearward compatibility issues.
