hjkl teaches Vim by letting you fix the text any way that works

A typo sits in a text buffer. The job is to fix it. Suddenly Vim has a purpose more immediate than collecting commands you might remember the next time a terminal traps you inside an editor (again, somehow).

hjkl’s own page calls the approach “learn Vim by doing.” The browser tool puts commands beside actual changes: delete a character, change a word, remove a line, move a sentence. You have something to accomplish before you have an excuse to admire a shortcut chart.

Each selected skill gets six edits. Two are guided, two supply a prompt, and two leave you independent. The training wheels come off gradually, which seems considerably more neighborly than handing somebody a keyboard and treating Escape as a personality test.

The useful detail is what counts as success. The page says any valid edit reaching the target text passes. That leaves room for an awkward first solution. You can complete the change before learning a smaller command sequence, instead of being told your perfectly corrected sentence is spiritually incorrect.

That distinction matters when a tutorial is teaching a tool with several routes to the same result. A task can be right even when the fingers took the scenic route. Whether the exercise recognizes that separates practicing an editor from guessing what its author wanted you to type.

The skill list also goes beyond movement. There are counts, searches, text objects, repeating edits, matching delimiters, and returning to marks. Those are changes a person can recognize in a file. A quoted phrase gives text objects a reason to exist; repeating a successful change gives the dot command a job.

For somebody who only needs to stop fumbling one frequent edit, picking skills is an appealing constraint. There is no requirement on the landing page to tour every corner before practicing the annoying part. The thing that wastes your time can become the whole session, without the ceremonial chapter on everything else.

The page specifies a desktop browser and a physical keyboard. A phone can display a lovely explanation of keyboard muscle memory while contributing very little muscle to it. It also says the tool is free, requires no account, and stores nothing. That last point makes a short practice session easy to start, while leaving no promise of a permanent learning history.

This is a narrower proposition than becoming fluent in every Vim feature. There is no reason to pretend six exercises certify somebody for an editor Olympics. They do give a familiar editing problem somewhere to happen with less at stake than a live configuration file.

A productive next practice would be the same sort of small change in a disposable file, checking whether the command still comes back without the prompt. The browser can tell when the sample text is correct; the next real typo still has to find its way under your fingers.
