The K Menu
The K Menu is one of the central elements of .
There are five main groups in the K Menu which will be described now from bottom to top.

The KDE Group
This group is for the common things in the K Menu.
Logout 	 This entry is used to finish the session. It also shuts down the .
Lock Screen 	 With this entry you can lock your screen if you don't want anybody else to see your desktop. If you have set a screensaver, it will appear when locked, otherwise the screen will turn black. If you hit any key, you will be prompted for your user password. This is independent from the screensaver's password settings.
Configure Panel 	 In this submenu you can change the settings of , described in the Configuring section, add things to (see in Basics for more) and start the Menu Editor. You can also reach the Help Menu, but as you are reading this, you probably found it yourself.

Run Command
This will bring up a small but powerful application start dialog.
In the standard case, you just type in a command and press Enter or click Run. But there is also an Options button which will bring up some starting options to the command window.
Run in terminal 	 Checking this box will let the application start in a terminal which means that you aill be able to see any commandline messages the application may give.
Run as a different user 	 If this box is checked, you can specify a user with whose permission the application should run in the Username textfield. If you specify another user, you will have to give a password at the box below.
Run with different priority 	 Check this option to run with a different priority. A higher priority will tell the operating system to give more processing time to the applications. You can use the slider to change the priority. If you want to give your app a higher priority than the default one (middle position), you will need to enter the root password below.
Scheduler 	 The Scheduler is the part of the operating system which processes will run and which have to wait. Usually, an application will run with normal schedule, which means it can use the processing time it gets from the operating system, but you can also set it to Realtime. This means that the application has all the process time until it gives it away. You will need to enter the root password to use Realtime.
This can be dangerous. If the application hangs and can't give up the processor, the complete system might hang.

Browsers
This group contains some very useful browsers. It can also contain dynamic menus as described in the Menus section of 's settings.
Quick Browser 	 This submenu contains quick browsers for three very useful directories: home, root, and system configuration.
Recent Documents 	 This menu shows the most recently used documents (works only with applications for the moment). Clicking the element Clear History will remove those entries, what may be useful for privacy reasons.
Bookmarks 	 This submenu shows your personal bookmarks just like does. Refer to the Handbook for more help on this.

The Application Group
The submenus for application starting are located in this group. You can use to add, remove or move the entries. Applications will have a short description if the option Detailed menu entries is enabled in the settings.

The most recently used applications
This group holds either the most recently or the most frequently used applications. See the Menus Configuration section for more about that.
