La réponse de Love Randy (+1) et je viens d’apprendre à propos des blocs de tags! Ceci est juste une réponse supplémentaire.
Donc yit signifie "bloc de balises internes" et vat "passe en mode visuel et sélectionne un bloc de balises (entier)".
Ceci est juste pour ceux qui sont trop paresseux pour lire le fichier d'aide:
Tag blocks *tag-blocks*
For the "it" and "at" text objects an attempt is done to select blocks between
matching tags for HTML and XML. But since these are not completely compatible
there are a few restrictions.
The normal method is to select a <tag> until the matching </tag>. For "at"
the tags are included, for "it" they are excluded. But when "it" is repeated
the tags will be included (otherwise nothing would change). Also, "it" used
on a tag block with no contents will select the leading tag.
"<aaa/>" items are skipped. Case is ignored, also for XML where case does
matter.
In HTML it is possible to have a tag like <br> or <meta ...> without a
matching end tag. These are ignored.
The text objects are tolerant about mistakes. Stray end tags are ignored.
