Its usefull, if you f.e. read a documentation of a newly downloadedprogram in MultiView etc.
Imagine there are links to a website, a youtube video or the email addressof the author in this documentation.
Previously you had to mark the text with the link, copy it to theclipboard, then open the appropriate program and paste the text there.
Quiet uncormfortable, heh?
Now, you can just mark the text and copy it to the clipboard. Thats all!
My SmartClipboard compares the copied text with the defined patterns andexecutes the corresponding command!
