Creating .desktop files to use on the “Open with other application” tab
The interface for associating a file type to a particular application has changed in 11.10 due to the introduction of GNOME 3. In previous versions, if I went to file properties, and went to the Open With tab, it would be possible to browse /usr/bin for the program I wanted. Now, the Open With tab only provides a list of applications, and that list is not complete. If the application I want is not on the list, I don't know how to change the file association. For example, I want .tex files to open with TeXmaker, not Gedit. I get an 'Open with TeXmaker' option in the right-click menu, but TeXmaker is not on the list of programs I can permanently associate to the program. I'd also like to associate .deb files to gdebi-gtk because I don't like waiting forever for Software Centre to start.
