How can I change my default applications in Oneiric to a custom application (not on the list in system info)? I'm not talking about the default applications to open filetypes - I mean the ones that appear in the dash and open when I hit keyboard hotkeys.

This isn't really possible without editing the source code directly: askubuntu.com/a/37721/235 –  Jorge Castro Dec 14 '11 at 22:40

If you're referring to the 4 icons in the bottom row of 'Dash home' all but "View Photos" can be easily set to use a custom .desktop, (custom command), & display the icon specified in that custom .desktop.

"Browse the Web; Check Email; Listen to Music" are all controlled by specific mimetypes, manually setting a custom made .desktop to the default for those mimetypes, typically in ~/.local/share/applications/mimeapps.list, will change what is shown in the Dash home screen.

The 'controlling' mimetypes are - (In the [Default Applications] section

Browse the Web; x-scheme-handler/http=

Check Email; x-scheme-handler/mailto=

Listen to Music; audio/x-vorbis+ogg=

If you wanted to see totally different things available in that 2nd row then you'd need to make changes to the source code.
