When Sticky Keys is enabled, how do you quit a key sequence after pressing a modifier by accident?
https://help.gnome.org/users/gnome-help/stable/keyboard-shortcuts-set.html.en suggested Backspace to reset, and Esc to cancel a Sticky Keys sequence, which did not work.
EDIT:
Pressing a modifier twice does not disable it.
Environment is Gnome Shell 3.22.3.
I am enabling Sticky Keys via the Universal Access applet.
