Solução Simples
Crie dois atalhos, um para desabilitar a tecla Super e outro para restaurá-la à vontade.
Vá para Configurações do sistema - > Teclado - > Atalhos - > Personalizado e clique no botão + . Nomeie o novo atalho "Disable Dash". O comando é
gsettings set org.compiz.unityshell:/org/compiz/profiles/unity/plugins/unityshell/ show-launcher 'Disabled'
Para criar um atalho para reativar o script, repita as etapas acima, mas o comando deve ser
gsettings set org.compiz.unityshell:/org/compiz/profiles/unity/plugins/unityshell/ show-launcher '<Super>'
Uma solução de scripts
O script abaixo desabilitará a tecla Super quando o programa especificado pelo usuário tiver foco. Observe que o usuário ainda pode clicar no ícone de traço com o mouse para chamar o traço. O nome do programa deve estar entre aspas simples e exatamente o mesmo que aparece no Unity Launcher. Várias janelas podem ser especificadas no mesmo formato, separadas por espaço

Usage: disable_super_key.sh 'App Name 1' [ 'App Name 2' 'App Name 3' ... ]
The script disables the Super key for the specified set of applications
under Ubuntu's Unity environment. The list of windows must be space
separated, each app name single quoted and exactly as it appears on the
launcher (or as it appears in the .desktop file of that app), so spelling
and spacing matter.
Note that the script only disables the Super key as shortcut for Dash.
The user still will be able to invoke Dash by manually clicking on the
Ubuntu icon in the launcher
