Konsole does not use global keyboard shortcuts to change tabs.
In KDE system settings, you can change the keyboard shortcuts to change tabs in many applications, especially browsers (konqueror, firefox....).
Konsole, however, does not follow this global settings but has its own shortcuts that can be set for the same task.
It probably should follow the global settings.
Also, provide the user with a list of global shortcuts is affecting the use of konsole.
