On en.wp, Shift key on first keystroke causes the cursor to jump to the bottom
Closed, DeclinedPublic


When editing en.wikipedia, the shift key on the first keystroke causes the cursor to jump to the bottom.

Steps. Edit an article. Place cursor where you want to edit the text. If the first keystroke involves using a shifted character, like a capitalized letter at the beginning of a sentence or a common wiki character like { or |, it will instead cause the cursor to jump to the last position on the window and will write the keystrokes.

Solution, cut or delete the error and return to where you intended to work.

I edit using Safari v10.0.1 on a Mac OSC 10.12.1

This is similar to but distinct from the common wikipedia editing problem that has plagued me for almost ten years where, after placing the cursor, it will disappear if the mouse does not remain hovering over the edit window. In the case above, it does it even when the mouse is still hovering over the edit window. This has been happening for about a month. ~~~~

Hi @Trackinfo, thanks for taking the time to report this!

Edit an article.

Is this about classic wikitext editor? Or VisualEditor?
I fail to reproduce - does this also happen with other browsers? Which ones did you test?

Also see How to report a bug for more info how to structure bug reports Thanks!

I tested this also on Chrome with exactly the same results. This is what I believe is the classic editor. I am not doing anything fancy. I don't know anything about the visual editor.

Appears to be the same issue as T154169: Shift key faulty behavior on English Wikipedia when using source editor in Internet Explorer, which was noticed in an unspecified version of Internet Explorer.

@Trackinfo: Have you only noticed this issue at English Wikipedia? Does it occur if you edit a page on another wiki?

I have a feeling this is a problem with a gadget at enwiki...

I tried an edit on the fr.wikipedia and it did not produce the same error. Curiously it also did not produce the long term error I described (about the cursor outside of the text area). So apparently both of these problems are on en.wikipedia rather than wholesale

@Trackinfo: With which browser, and does this also happen with all gadgets disabled in your user preferences?

@Aklapper and @TTO: today I tried to produce the error again in IE and Edge, and the error did not recur for me in those browsers. I will post here if I encounter the issue again. Note that I did not test Safari, which was also mentioned as a product where this bug occurs.

Closing for the time being as non-reproducible. Please reopen with additional information if this still happens / happens again. Thanks!
