Some keyboard shortcuts require that one key (a modifier key) is kept
pressed constantly (this applies to Alt,
Ctrl, and Shift)

the system regards those keys as staying pressed after being pressed
once. To enable sticky keys, activate . If is selected, the keys do not

2.4.2 Changing Your Password

from time to time. To change your password:

are automatically managed by the applications that create them. Whenever
any GNOME application that uses GNOME Keyring needs to access passwords

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

of Keyring Manager.
The secret is removed from the list.
