Share current page to ChatWorkExtension that allows you to share the page being displayed with chat work.
The same function as the official "share with chat work" button (http://www.chatwork.com/ja/share/) is realized on the page where the button is not installed.
If you select a character string in the page, quote the selected range.
By setting it as an option, it is also possible to open a share page directly to KDDI ChatWork.
