Cant find corresponding entries for switch-windows-backward, switch-windows-all and switch-windows-all-backward in the mate-keybinding-properties

[Norbert]

Steps to reproduce:
1. Have Ubuntu MATE 20.10 installed
2. Execute the command and get the output shown below

    $ gsettings list-recursively | grep Tab | grep Alt | grep mate
    org.mate.Marco.global-keybindings switch-windows-backward '<Alt><Shift>Tab'
    org.mate.Marco.global-keybindings switch-windows-all '<Control><Alt>Tab'
    org.mate.Marco.global-keybindings switch-windows '<Alt>Tab'
    org.mate.Marco.global-keybindings switch-windows-all-backward '<Control><Alt><Shift>Tab'

3. Try to find corresponding entries for switch-windows-backward, switch-windows-all and switch-windows-all-backward in the mate-keybinding-properties

Expected results:
* there are corresponding entries for switch-windows-backward, switch-windows-all and switch-windows-all-backward in the mate-keybinding-properties

Actual results:
* there are no corresponding entries for switch-windows-backward, switch-windows-all and switch-windows-all-backward in the mate-keybinding-properties. Only <Alt>+<Tab> is shown as Window Management, Move between windows, using a popup window.
