Après avoir installé Shellshape ( voir http://links.simonlefort.be/?TYVZQA ), il y a certains conflit de raccourcis dont le verrouillage de l'écran via "Super+L".

Pour changer les raccourcis par défaut de Gnome3, on va dans les Paramètres > Clavier > Raccourcis.

[edit: Je ne l'ai pas gardé, il y a des bugs...]

Un plugin pour Gnome 3. J'ai l'impression qu'il faut un peu d'habitude pour intégrer les différents raccourcis claviers.

Je copie la liste des raccourcis claviers :

win+t tile the current window
