Description Luis Lezcano Airaldi 2015-04-27 17:40:08 UTC 
I'm not sure if this is the right component where to post this bug.

I was experiencing this issue in Kate https://bugs.kde.org/show_bug.cgi?id=345504 (Keypad keys not working) and I was able to track down what I think is the problem.

I think some components (the shortcuts configuration dialog in systemsettings, Kate and other apps) are ignoring the Keypad modifier from Qt (Qt::KeypadModifier).

To test this I downloaded the KTextEditor source code and replaced the default shortcut for PageUp with "Qt::KeypadModifier + Qt::Key_PageUp" in src/view/kateview.cpp, like this:

a = ac->addAction(QLatin1String("scroll_page_up"));                         
a->setText(i18n("Scroll Page Up"));                                         
ac->setDefaultShortcut(a, QKeySequence(Qt::KeypadModifier + Qt::Key_PageUp));                                                                                                          
connect(a, SIGNAL(triggered(bool)), SLOT(pageUp()));                        
m_editActions << a;

Now it works as expected. Also, in the shortcut configuration dialog it shows up as "Num + PageUp", instead of just "PageUp" as before.
Of course, the same applies for the other keypad keys: Home, End, Insert, Del and PageDown.

Another thing: I am also having this bug https://bugs.kde.org/show_bug.cgi?id=343665, but I can't tell if it is related or not.

I forgot to mention I'm running ArchLinux with KDE Frameworks 5.9.0 and Qt 5.4.1
Comment 2 Luis Lezcano Airaldi 2015-04-27 19:24:21 UTC 
No need to modify source code. As a temporary workaround I manually sanitized ~/.config/kdeglobals (which is getting malformed because of Bug #343665) and added "Num+" in keypad bindings like this:

[Shortcuts]
BeginningOfLine=Num+Home
EndOfLine=Num+End
Next=Num+PgDown
Prior=Num+PgUp

Now it works as expected with no code change required.
