Inspired by usage of SE sites, I frequently have to flag Off topic post and write a comment telling OP to make the post on a different SE site. Usually, I go to the bottom of the page to retrieve the link from there. What I find to be useful is, I could click some shortcuts and a list of pre-set values will be shown and I could scroll those using my keyboard and press enter and that same text will be pasted where the shortcut was initiated from
Does such a Plugin exist for Firefox, or any Windows based application that would help me to achieve similar outcome?
