Right-click on a URL to open it in your web browser.

CRT and SecureCRT will recognize most URLs. Just right click on the URL and select "Open URL" from the context menu. If the URL isn't a standard URL or if the application fails to recognize it, you can select the URL, right click and select "Open Selection as URL".

As of version 6.5, there's also a global option that allows URLs to be opened by CTRL+clicking them. The option can be set from the Global Options dialog, under the Terminal category.
