Aren't the docs supposed to clear up issues like this? Are they insufficient?

(In reply to Helder from comment #0)

In its current form I'm always wondering "check what?" and "switched what?"

Can't them be replaced by sentences like "Switched from VisualEditor" and
"Check VisualEditor errors" or something better?

Space is at a premium where tags are involved. They occur in page histories, recent changes, watchlists, diffs, IRC feeds, and other places. Brevity is important.

Also, as Alex says, if this is just fixing the qqq messages to make these clearer, this can be done at TranslateWiki.net without the need for a bug.
