Familiarize yourself with adding actions to buttons. 

The command to open a web page (URL) in your browser (or to open it in the background) is openurl

The parameters are;

• url=<url of web page>
• bg=true (optional)

The optional bg parameter opens the url in the background - nothing shows on screen.

The optional delay specifies a time (in milliseconds) to wait before running the command.

Example - open the UP Deck documentation in your browser.

Example - silently trigger an action on a remote site.
