Edit war?
Fragment of a discussion from User talk:Ainali
Not directly, no (but the help text in the editor leads to w:sv:Wikipedia:VisualEditor/Användarguide). They see "Redigera" (Edit) and "Redigera wikitext" (Edit wikitext) (n.b. not "source"). And then the buttons to switch between editors while editing is "Visuell redigering" (Visual editing) and "Wikitextredigering" (Wikitext editing). So the most consistent text to use on the tabs would be these last two.
Yeah, it's kind of a mess. We might need you at https://phabricator.wikimedia.org/T256166 and related tasks. Some communities translate wikitext as wikicode, which helps a bit. (This kind of thing makes me wish for WordPerfect 5.2 on MS-DOS: I keep thinking about "Show codes".)
