How long a key is pressed and held before being recognized as valid input
Whether the keyboard can be used as a mouse
Whether key combinations that use Alt, Ctrl, and Shift can be duplicated with “sticky keys”
You can then define various settings for keys:
Some keyboard shortcuts require that one key (a modifier key) is kept pressed constantly (this applies to Alt, Ctrl, and Shift) while the rest of the shortcut is typed. When sticky keys are used, the system regards those keys as staying pressed after being pressed once. To enable sticky keys, activate . If is selected, the keys do not “stick” anymore when two keys are pressed simultaneously. The system then assumes that the keyboard shortcut has been completely entered.
To prevent accidental typing, activate . Set a minimum time limit that a key must be pressed and held before it is recognized as valid input by the system.
To prevent double typing, activate and set a minimum time limit for accepting two subsequent keypress events of the same key as the input of two individual characters.
To use the keyboard as mouse, switch to the tab and activate . The mouse pointer is controlled with the arrow keys of the number pad. Use the sliders to set the maximum speed of the mouse pointer, the acceleration time until the maximum speed is reached, and the latency between the pressing of a key and the cursor movement.

GNOME Keyring Manager provides an interface for viewing secrets stored in keyrings on your computer. Secrets include such items as:
Passwords
Wireless credentials
Certificates
Credentials for logging in to another computer
Most users will not need to use GNOME Keyring Manager because secrets are automatically managed by the applications that create them. Whenever any GNOME application that uses GNOME Keyring needs to access passwords or credentials stored there, a check is made if the keyring is locked or not. If it is locked, you will be prompted for the master password to unlock the keyring.
To open Keyring Manager (independent of any application interaction) press Alt+F2 and enter gnome-keyring-manager.
To delete a secret:
In the list of keyrings on the left side of Keyring Manager, click .
Click the secret you want to delete in the list in the top right area of Keyring Manager.
Click .
The secret is removed from the list.

To open the Keyboard Shortcuts tool, click +++.
To change the shortcut keys for an action, select the action and then press the keys you want to associate with the action. To disable the shortcut keys for an action, click the shortcut for the action, then press <—.
