Cannot navigate the cursor with the numeric keypad while editing in Kate - the numeric arrows (when numlock is off) does not work. Also, although "numeric keypad should function like in MS Windows" is selected in KDE settings, I cannot quick-select text by pressing SHIFT+HOME or SHIFT+END to highlight a line. When numlock is on, I can use numeric keypad for number input. The above-mentioned functionality works perfectly through KDE and other apps. Reproducible: Always Steps to Reproduce: 1. Open kate 2. Type any sentence 3. Ensure numlock is off. 4.1 try to move cursor with numeric arrow keys - not working 4.2 try to highlight a line (from start or end) by pressing SHIFT+HOME or SHIFT+END Actual Results: Nothing happens - when numlock is off, its as if Kate does not know that numeric keypad exists. Tried with both laptop keyboard (has built-in numeric keypad) and plugged in USB keyboard - neither works. Both work for the rest of KDE though.
I can confirm this is an issue for me, too, in Ubuntu 15.04 / Plasma 5.2.2 / Qt 5.4.1. Also, I can confirm that this is not an issue in other applications (including other KDE applications) for me, such as Firefox, LibreOffice, KMail, and Yakuake. My system is a crossover from Ubuntu-Gnome by installing the kubuntu-desktop package. I've noticed that both FCITX and IBUS are running. I have absolutely no idea whether or not this would have *any* effect whatsoever, it's juts an oddity I thought I'd note in case it has any effect.
I have the same issue on Arch Linux with Kate 5.0.0 / KDE Frameworks 5.8 / Qt 5.4.1 I tried changing the mappings and some keyboard settings in systemsettings but it didn't work.
I also found that the shortcuts are not saved when setting both a main and alternate shortcut, so I think this bug might be related to https://bugs.kde.org/show_bug.cgi?id=343665
Same happends to me (in two machines). Its very a frustrating when fingers allways hits those keys as a "brain-automatically" and nothing happends. Ins (0) and Del (,) did not work either. Kate is 5.0.0 and Kubuntu 15.04 in use. Please fix this!
Having the problem, too, on Kubuntu 15.04.
My laptop doesn't have physically separate Home and End keys, so I rely on always keeping Numlock off and using the keypad. This is a very serious usability issue for me. Haven't there been enough reports to at least Confirm this bug?
Same in KWrite 5.0.0 on Kubuntu 15.04 - very frustrating bug.

I am very sorry for your inconveniences, but I can't reproduce that at all with current KF5 based Kate/KWrite.
I also see the problem on a system running NetRunner Osmandias with both kwrite and kate. One hint, perhaps, The navigation keys DO work when in VI input mode. They do not work in Normal Input mode.
I can reproduce this on Kubuntu and KF5 HEAD I have done a couple of minutes investigation into this and I suspect that the Qt::KeypadModifier might be the root of the problem.
I think I was right about Qt::KeypadModifier :) The thing is, cursor movement is handled by shortcuts set up in KTextEditor::ViewPrivate::setupEditActions() Here up/down/... is assigned a QAction with it's default shortcut Qt::Key_Up/Qt::Key_Down/... Now on Kubuntu, and Swedish layout at least, the numeric key pad buttons come as Qt::Qt::KeypadModifier+Qt::Key_... This means that they do not match the shortcut and do not trigger the slots. I have tried adding more actions with the modifier and it works, but then we would have to duplicate all key-combinations also :( The same holds if we just add alternate shortcuts. It is doable but not nice. I also tried to play around with the event handler to just remove the modifier, but I have not succeeded yet to get the actions triggered. I wonder why these are actions and not handled in keyPressEvent()...
I when through all the edit actions and added alternate shortcuts, but then the shortcuts from scripting still do not work... And then thinking if this really is a Qt bug as it used to wok in Qt4, I looked around and found https://bugreports.qt.io/browse/QTBUG-33093 and https://codereview.qt-project.org/#/c/95219/ which was merged today to Qt5.5 (could be included in the 5.5.1 release).

I've been reading all of this and now I'm confused. Which version of kate has this bug been fixed on? Where can I get it? Thank you
It is a bug in Qt not Kate. The reason it works in some KDE applications is that they use keypress events directly and not QAction shortcuts. So you have to update the Qt version to at least 5.5.1 (which is not released yet at the time of writing)
