i do not know why it isnt working i use opera and opera i linked the dock icon to the shortcut i dont know what is the problem

You **know** it works for other shortcuts in the dock, don't you? Then perhaps you should rephrase the tile of the topic so it's a bit more specific... what do you think?

Anyway, can you please post a screenshot of the Docent Entry Properties dialog for that particular item?

Also, does the item get a running indicator symbol after using it to launch (Opera?)
