How to change the keyboard settings in KDE 4

This page explains step-by-step how to change the keyboard settings in KDE 4 for Linux. 'Bounce keys' and 'slow keys' provide you with the ability to control the pace of repeated keystrokes and to slow down the acceptance of keystrokes (if required), helping you to avoid accidental keystrokes.

Changing the keyboard settings in KDE 4

Set up bounce keys or slow keys

Step 1: Open the 'Keyboard Filters' tab

Click on the 'K' icon on the menu bar, or press Alt + F1, to open 'Kickoff' as shown in Fig 1.

Click on 'Computer' and then 'System Settings', or use the arrow keys to select these and then press Enter, to open the 'System Settings' window shown in Fig 2.

(Some setups may vary. In this example, 'System Settings' is also available from the 'Favourites' tab, as shown in Fig 1.)

Click on the 'Accessibility' icon or press Tab to enter the main window, and then use the arrow keys to navigate to 'Accessibility' and press Enter.

In the window that opens, shown in Fig 3, click on the 'Accessibility' icon, or press Tab until the pane on the left is highlighted, then use the down arrow key to move to 'Accessibility'.

Once the 'Accessibility' settings are visible, as shown in Fig 4, click on the 'Keyboard Filters' tab, or press Alt + K. You can now turn on bounce keys (see Step 2) or slow keys (see Step 3).

Step 2: Turn on bounce keys

'Bounce keys' are helpful for people who find they hold a key down too long and so get a string of unwanted characters. 'Bounce keys' introduces a delay after a keypress, during which time the same key cannot be used again.

Tick the box next to 'Use bounce keys' by clicking on it, or by pressing Alt + N. Once this is done, you can adjust the time the computer waits before letting you repeat a keypress. To do this, drag the slider below 'Debounce time', or press Alt + E then use the arrow keys, to adjust the time. The default time is 500 milliseconds (half a second).

Click on the 'Apply' button or press Alt + A to save your changes.

Click on the 'Overview' button or press Esc to return to the previous screen. Click the 'Close' cross or press Alt + F4 to return to the KDE desktop.

Step 3: Turn on slow keys

'Slow keys' are helpful for people who tend to accidentally press keys they don't want. When 'slow keys' is turned on, a key has to be held down for longer.

Tick the box next to 'Use slow keys' by clicking on it, or by pressing Alt + U. Once this is done, you can adjust the time you need to press down on a key before it is recognised. To do this, drag the slider below 'Acceptance delay', or press Alt + Y then use the arrow keys, to adjust the time. The default time is 500 milliseconds (half a second).

Click on the 'Apply' button or press Alt + A to save your changes.

Click on the 'Overview' button or press Esc to return to the 'System Settings' window. Click the 'Close' cross or press Alt + F4 to return to the KDE desktop.
