Making your own keyboard app-launcher in Ubuntu

One day I got this message in gmail ubuntu-id mailing list that someone requested a how-to add a keyboard app-launcher in Ubuntu. i tried to give him a closer solution, by pressing Alt+F2 and typing application name; or by adding deskbar to main panel, pressing Alt+F3, and then typing three fore-letter of the application you want to run.
is there simply just one shortcut for all these?

Yes, there is...

1. Go to terminal, run :

gconf-editor

2. In Configuration Editor window, Go to apps/metacity/keybinding_command.
click command_1, and click it once at the it's "value" column, type the application you want.
for example openoffice writer, which the command is ooffice -writer.
then press Enter.

you can also use other command_(1 to 12) that still has no value.

3. Go to apps/metacity/global_keybinding.
Find run_command_1, dan click it once at it's "value" column.
Add your own shortcut, which is not have used before. for example Ctrl+Shift+F5. Type it like this <Ctrl><Shift>F5

Close the Configuration Editor window.

4. Now try pressing Ctrl+Shift+F5.

Crazy Penguin Catapult

Hey you, Linux Lover, have you played Crazy Penguin Catapult yet? Yes, it played The Tuxes as a platoon of soldiers trying to fight against a bunch of dirty bears and rescuing their friends. There are more 30 level that you have to pass to conquer this game.

At the beginning of each level yo have to send the tux soldiers with a catapult to the enemy's base, and destroy the dirty bears by sending them as a bomb.

Crazy Penguin Catapult is a flash based game that very funny and quite entertaining too. It took me about an hour to get drown playing this game and forgetting anything.

1. Go to System/Adminstration/Update Manager.

or simply by clicking red arrow with exclamation mark ( ! ). You can see how many updates available if you placed the pointer on the arrow.

2. The Update manager window will be opened and showing all updates available.

Since we only update the firefox 3.0, right click on update list, and pick "Uncheck All".

3. Pick Firefox 3.0 related packages to update the Mozilla Firefox application. Then click "Install Updates" button. You will prompted for admin password to go through.

4. Just wait the update process to be completed. Then, close Update Manager window.
