I prefer to use

from the command line rather than the application manager to remove applications, as that way I know all traces of the program will be removed.

However sometimes it is an issue finding the right <app-name>. Right now I have one of those annoying pseudo-apps created by someone using the Ovi App Wizard installed and I want for dear life to get rid of it. The title of it is "Forex Trends &amp; Currency Ne" (yes just like that) and I have tried a few methods for finding out this app's name:

(1) Looking in Settings > Applications > Manage Applications to find out information about the app. No information as to its name there.

(2) Tried

and searching the file "list" for any names with "forex" in the name; no luck.

(3) Tried

and again searching the file "list2" presented no obvious solution.

Is there some general method we can use, knowing an application's title, to get its name?

Have you tried looking into the the .desktop file?
It should be located in
