Just a simple mod I quickly cooked up in less than an hour or so. It adds some buttons to the right the screen, that appear when you move your cursor to the right, that let you search on various websites for whatever you have on your text bar. Left clicking the buttons opens that page on your browser, right clicking changes the text on your text field to the URL.
You can add your own websites using the config file. By default it looks like this:
# Watmean config, add websites here. Format: (name)>(url)
# Set %text% to be the text you put in.
# Do NOT include http:// in the URL, that is added automatically.
