. If no other modifications are performed, the screen is inverted when a system bell rings ( is activated by default). The duration of the visual bell can be adjusted with the slider. Instead of the inversion, the screen can be set to flash. To do this, activate and then select a suitable color in the color editor by clicking the color bar.Sticky Keys:Some shortcuts require a key to be held down (this is the case with Alt, Ctrl, and Shift) while the second part of the shortcut is entered. If sticky keys are used, the system considers these keys to be pressed continuously even if they are pressed only once.
Slow Keys:Determines if and to what extent the system delays the output of characters on the screen when a key is pressed. The longer the interval adjusted with the slider is, the longer a key can be pressed without triggering a repeated output of the respective character on the screen.
Bounce Keys:If you activate this option, pressing a key twice is interpreted as two characters only if the interval selected with the slider has elapsed. If a key is pressed twice inadvertently, this is ignored.

.This module lets you configure options that are specific to your location, such as language, currency, and the date format. The settings in this module apply only to KDE applications. Other applications, such as OpenOffice.org, might need to be configured separately.
Figure 70 KDE Control Center Country/Region & Language Dialog
All regional system settings can be configured using these five tabs:
Locale: Use the drop-down menu to select the desired country from the list. Settings such as the language, numbers, currency, time, and date are automatically set to suitable values. A preview of all current regional settings is displayed at the bottom of the page. For example, to use the regional settings for the U.S. but use Spanish as the system language, click Add Language to select this language and add it to the list of available system languages. To remove a language, select it from the list and click Remove Language.
Numbers: To use different number settings than the default settings associated with the country selected under Locale, configure the decimal symbol, thousands separator, positive sign, and negative sign. The decimal symbol and the thousands separator for currencies are configured separately on the Money tab.
Money:Configure all currency-related settings that should differ from the default settings for the selected system language. The position of the currency symbol and the prefix for positive and negative amounts are arranged in such a way that the currency symbol precedes the prefix and the amount.
Time & Date: Sets the time format, date format, short date format, and first day of the week.
Other:Sets the default paper format and measurements. On a U.S. system, the default paper format is US Letter and the imperial system is used for measurements.

.Use this module to configure Kxkb, a keyboard layout switching utility that uses the X Window System* xkb extension. It allows you to switch between different layouts using a tray indicator or a keyboard shortcut. You can enable/disable keyboard layouts through this dialog, and add more. Some of the more powerful features are the ability to configure switching of layouts globally, per application or per window.
