I have encountered the bug https://bugs.kde.org/show_bug.cgi?id=386265, i.e., kdevleop and katepart have the same shortcuts (F9, F10, F11).

To avoid this problem I tried to change the katepart shortcuts to None but when I restart kdevelop the katepart shortcuts are reset to default.

Are the katepart shortcuts used by kdevelop saved for kdevelop only? I mean, do every application using katepart have its own katepart shortcuts config file?

If I open Kile for example, those shortcuts (F10, F11) are not set, while in kdevelop they are.
