Dear Robert, Good question.
I discovered that the PyQt5 I had in the Lubuntu machine was from pip3. So it had the shortcuts working, but had the problem with overlay scrollbars that make the window crash and throw the error here https://bugs.launchpad.net/ubuntu/+source/qt4-x11/+bug/805303 . Uninstalled and installed the python3-pyqt5 package and had the non- working shortcuts back. Sorry for mixing things and now things makes more sense! -- You received this bug notification because you are a member of Unity API bugs, which is subscribed to sni-qt. https://bugs.launchpad.net/bugs/1380702 Title: No keyboards shortcuts in QT apps Status in appmenu-qt5: In Progress Status in Canonical System Image: In Progress Status in sni-qt: New Status in qtbase-opensource-src package in Ubuntu: In Progress Bug description: In some apps built using QT4 & 5, menu shortcuts are greyed out and inoperant. Only alt and FKeys-based shortcuts work. Others, notably ctrl+c for copying, do not. This is quite serious ; mail me for more details.
