Once you have copied a web address (URL) from another application, you can paste it in
the Web panel, just by clicking the Paste button.
If it's a valid URL, the web page will be automatically loaded.
Note :
The Paste button is enabled if the clipboard contains some short text. Before clicking, you can verify
that it's the right URL you copied, by looking at the tooltip on the Paste button (hover your cursor
above the button, about half a second).
