¿Title seems contradictory? Let me explain. I did find how to customize Workbench shortcuts, for example in the following link: Customizing Keyboard Shortcuts in MySql Workbench.
I think it was the update of the Workbench, or the whole going to Ubuntu 14.10, after which the modified shortcuts stopped working. If I open the file main_menu.xml, I can see the shortcuts are indeed modified the way I want them to be, but the program won't recognize them and uses the default ones.
Would anyone know how to fix this? Please help.
