My English is not so good, so don't hesitate to ask again if you don't understand what I wrote. I use Ubuntu and Opera on my laptop. And i trying to create web-application by left panel.

[Desktop Entry]
Version=1.0
Type=Application
Name=Name
Comment=Комментарий
Exec=opera URL
Icon=scr to icon
Path=
Terminal=false
StartupNotify=false

This file (~/.local/share/applications/name.desktop) opens two pages in browser : basic and desired. What key is needed to open the desired page only? Where can I read list keys?
Understandably?
