You will see the Vim home page in the browser. That's OK. Then, it'll be much quicker if a menu icon is defined like this. Triple crick on url and click icon, then you'll get the url in your browser. But inserting a new icon is not easy, so replace existing one. Following is the part of "$VIM_HOME\vim\vim61\menu.vim" that shows "Open New" icon replaced with "Start Explore" definition. The named buffer "w" is used for not disturbing clip board. Remove comment on Tool tip line.
