I just installed Kubuntu 14.04 and I'm in the process of customizing it.
I replaced the default Application Launcher with the traditional-style Application Launcher Menu. With this application launcher, you can assign shortcut keys to specific applications (by navigating to the Advanced settings for a particular application in the Edit Menu view).
I assigned shortcut keys to a few applications and tested, and everything worked. Then I went through every item in the System Settings and set my preferences. But somewhere along the way I disabled the application launcher shortcut keys. In the Menu Editor, they are still set as I defined them, and under the "Global Keyboard Shortcuts" system config in the "khotkeys" section, I also see them defined. But they just don't work anymore.
Is there some System Setting that would cause this to be disabled? How do I re-enable these shortcuts?
