Determine how the system should react to clicks and double-clicks. The default setting for the KDE desktop is a single click for opening files or folders and a mouse pointer that changes its appearance when it is moved over icons. If you want icons to be selected automatically in addition to the single click, activate the respective option and set the delay for this selection. To use the Windows-typical double-click for opening files and folders, select. Finally, set the size and color of the pointer and the visual feedback on activation.
Configuration options of thetab:
The pointer acceleration defines the relation between the movement speed of the input device (mouse) and the speed of the pointer on the screen. The higher the selected factor is, the more difficult it is to control the screen pointer. The threshold (in pixels) specifies the distance the pointer must cover before the indicated pointer acceleration is activated. In this way, control the mouse pointer easily when covering small distances and cover large distances on the screen with small movements.
Here, set the maximum interval between two mouse clicks that should still be interpretted as a double-click.
The object selected with a click is moved if you move it by the distance in pixels specified inwithin the period specified in .
If you have a wheel mouse, specify the number of lines the image should scroll per wheel “tooth”.
To be able to navigate the mouse pointer with the arrow keys of the number pad, activate this function underand customize the parameters according to your needs.

The section is then activated in the lower part of the dialog. Three radio buttons offer the basic configuration options none, default, and custom.
Existing schemes are write-protected, allowing restoration of the default values at any time. Save your own modifications by clickingat the top right and entering a name for your custom scheme. The new scheme is then listed in the selection menu.
Under, you can only configure standard actions available in all applications. Program-specific shortcuts must be configured in the program itself via -> .
The settings in this module facilitate the access to the system for users with hearing problems or motor disorders. This module contains theand tabs.
System bells can be communicated to the user in a visible or in an audible form. The default setting is the audible variant with. To configure a specific sound, activate and use to select a suitable sound from the list.
If you want system bells to be communicated visually to the user, activate. If no other modifications are performed, the screen is inverted when a system bell rings (the radio button 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 flash. To do this, activate and select a suitable color in the color editor by clicking the color bar.
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 only pressed once.
Here, determine 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.
If you activate this option, pressing a key twice is only interpreted as two characters if the interval selected with the slider has elapsed. If a key is pressed twice inadvertently, this will be ignored.
