Due to a bug/glitch, I can't use GNOME Flashback for a while. I am forced to use the new GNOME Shell layout. I'm finding it a large leap back in usability. I am not able to customize it the way I can with Flashback. It tries to pretend I am on a tablet. But that's a different story.
I have 2 versions of IntelliJ IDEA installed. When I find "idea" in the screen under Windows key ("Activities" overview), only the older version is found. I can add that through context menu. However, I haven't found a way to add the newer one. Or change the old one's path. I have tried various combinations of Alt, Shift, Ctrl and Super with both mouse buttons, but none gave me the "edit" menu item to change what the icon launches.
How can I add a custom command, or how can I change the path of an existing one?
