I'm using kde 4.0.1 but it wasn't on list.

fixed in more recent version.

*** Bug 168350 has been marked as a duplicate of this bug. ***

I am not sure whether Bug 168350 is really a duplicate. If it is, it holds a better description of the behavior.

KDE definitely gets meta, super and hyper wrong 
My description is as follows: first xmodmap output for modifiers

xmodmap:  up to 4 keys per modifier, (keycodes in parentheses):

shift       Shift_L (0x32),  Shift_R (0x3e)
lock      
control     Control_L (0x42),  Control_R (0x69)
mod1        Alt_L (0x40),  Alt_R (0x6c),  Meta_L (0xcd)
mod2        Num_Lock (0x4d)
mod3      
mod4        Super_L (0x85),  Super_R (0x86),  Super_L (0xce),  Hyper_L (0xcf)
mod5        ISO_Level3_Shift (0x5c),  Mode_switch (0xcb)


1. my (physical) windows-key produces a Super_L with xev, BUT
   when I use it in a shortcut combination in kde input action settings it
   will get recognized as meta_L. Nonetheless the resulting shortcut will work.

2. when I map my (physical) LControl-key to Hyper_L (and check it with xev) 
   and try to use it in a shortcut combination with another nonmodifier
   kde input action settings will recognize it as something weird 
   (strange nonlatin letters will appear in the shortcut-box) and
   the combination will get recognized as a single keypress, no modifier, but 
   as such it will work.

3. when I map my LControl-key to Super_L it will work as the windows key (see 1)
4. when I map my LControl-key to Meta_L and try to use it in a shortcut 
   combination, KDE will recognize it as an "Alt".. combination. Nonetheless 
   the combination will work, also when I press the real Alt.

Please reopen the bug, I'm using KDE 4.4.2 on Kubuntu 10.4., so it is definitely not repaired in a more recent version as stated above.

I'm still experiencing this problem in the KDE 4.5 RC on Ubuntu 10.04.

still in 4.5.1/ubuntu 10.10
seems like it's not a bug, but broken as designed.

Still not working in Kubuntu 12.04 (KDE 4.8).  Hyper, Super and Mode_switch are not treated as modifiers, but instantly produce funny looking characters when pressed in any "Customize shortcut" dialog.

My xmodmap is set up like this:

% xmodmap -pm
xmodmap:  up to 3 keys per modifier, (keycodes in parentheses):

shift       Shift_L (0x32),  Shift_R (0x3e)
lock      
control     Control_L (0x42),  Control_R (0x69)
mod1        Alt_L (0x40),  Alt_L (0xcc)
mod2        Hyper_L (0x86),  Hyper_L (0x87),  Hyper_L (0xcf)
mod3        Super_L (0x25),  Super_L (0xce)
mod4        Meta_L (0x85),  Meta_L (0xcd)
mod5        Mode_switch (0x6c),  Mode_switch (0xcb)

Rewrite of the global shortcuts kcm

Summary:
This is a total rewrite of the global shortcuts kcm from scratch. It uses an
abstract item model backend with a qml frontend. This resolves some issues the
old kcm inherently had because it just stacked KShortcutEditors. First it enables
a global serach/filter which either matches the component name, actions, default
or set key combinations across components. Secondly KGlobalAccel can have multiple
default/active key combinations for each action - the old kcm only exposed two each.
The new kcm displays all default or set key combinations.
The main visual structure is similiar to the old kcm. On the left there is a list
with all components but rather than divided into "Application Launchers" and
"Other Shortcuts" the sections are now called "Applications" and "System Services"
(cf. notifications kcm) and the components are now assigned whether the service
we find for a component is an application or not rather if the component was
added via .desktop file. In the main view the shortcuts are displayed. Each item
corresponds to one action. Initially each item is collapsed and shows the action
name and a list of the currently set key combinations for that action. In the
expanded form all default shortcuts are shown which can be activated or
deactivated and all other active shortcuts ("Custom Shortcuts"). It is possible
to change, remove or add new custom shortcuts.
The kcm and model communicate directly with the daemon over DBus. This removes
the need to awkwardly construct actions to pass to the KGlobalAccel API.
