The top one is from "The Dash", which is like a graphical alternative to tab-completion.

The bottom one is a Launcher icon. Click on it directly and the application runs.

Both get their information from .desktop files which contains a lot of metadata about each officially installed application. (For what it's worth that link is not going to be as useful as it is authoritative.) Some of the other links are going to be more informative: https://help.ubuntu.com/community/Un...ndDesktopFiles

They might be useful to know about in case later you want to make your own launcher or modify an existing one. But until then, they are not necessarily worth searching the web about.

Edit: your "deluge" file is probably /usr/share/applications/deluge.desktop
if you want to look

Thanks. I was going to follow the tutorial on how to create a .desktop file, but I noticed I can't create a new file in usr/share/applications, the options are greyed out, and under permissions it says "You are not the owner so you cannot change permissions." I'm not sure if for security they're best left as is. I keep hearing about how much more secure Linux is than Windows, and that you don't even need anti-virus. When I saw that the system locks even myself out of so many folders I assumed this was the reason it's so much safer from attacks.

If you're creating a new one for just yourself then you can put it anywhere, even in a subdirectory underneath your home directory. ~/Documents/Launchers/ might be an idea. If you are making one to share with other users on the same machine then there are several options about how to get the file into the system directory.

Beautiful, simply making a .desktop file with Exec=/usr/bin/deluge-gtk in it made it behave like the button on my launch bar. Thanks for all your help. I'll go ahead and mark this solved.
