BBcodeXtraIt ads a context menu to your right click that will give you all kinds of insert commands to use with or without items in your clipboard.
For example you copy the LOOOOONG link that you had and then right click and choose the bbcode xtra menu then move to clipboard to selections like: Image, URL, URL with name, quote, etc.
When you click it, it will place the item that is in your clipboard (last copy command) and place it in the message field here with the appropriate BBcode around it.
