I was trying to enter some text on my page on the weebly.com and in the provided field the keys hjkl did not work, and I saw "instructions" appearing in the left lower side of my computer about how these keys work as "scroll up," "scroll down", etc. I think it happened in some other editing fields on some other sites. I can't recall installing any plugin that would affect this. How can I disable this feature? I use Windows / and Chrome.
