Gnome 3 Tip - Quick Application Search

Posted 12-19-2011 at 12:07 PM by lumak

Gnome 3 will search the "comments" value of .desktop files when you start typing in the search box of the overlay screen. This search will include symbols and punctuation as well. This means that there are various ways to exploit the system and start grouping applications by symbols.

1. Copy your favorite applications' .desktop files from /usr/share/applications to ~/.local/share/applications
2. Edit the comments section to include a symbol for a group. E.G. ` ~ ! @ # $ < > . or anything you want... even a word.
3. Reset your session with Alt+F2 (type r, then enter) or log out and back in.
4. Press Alt+F1
5. Type one of your symbols
6. Observe all applications with that symbol in the comments appears.

Note, this is also the reason you can type something like 'music' and end up with several options relating to play music. Nothing magical, no special database, just edit .desktop files.

It would be nice if they added some customize options to the application launchers from within the shell instead of having to manually edit .desktop files.
