Hello,
I was lucky enough to get a brandnew wireless keyboard Dell KM5221W incl. wireless mouse.
It works right out of the box, nothing to complain about.
BUT:
The keyboard has some keys that I have not had on any other keyboard yet. Now I would like to find out if
1) siduction can separate the keys on a system level,
2) KDE is unable to separate the keys from other known keys.
The keyboard has four special function keys on the numblock area: a pocket calculator key (works, it launches KDE calculator), then a "CE" button that is supposed to clear everything in calculator program, a "+/-" key and a key that has a speech bubble on it.
Regarding the "CE"-key: I have had no success in konsole to tell the difference between this key and the standard "Entf" ("DEL") key for deleting one letter right next to cursor. Now I wonder if KDE or linux kernel is unable to tell the keys apart or if they are actually totally ok and do send same key code which I doubt.
Would KDE tell me different key scan code if I selected other KDE keyboard type? Would KDE tell me different key scancode if in konsole I load other keyboard type for konsole?
Which keyboard type would this have to be?
How can I identify for sure the difference between "CE" and "DEL" key. I have already tried evtest which gave me exactly same code for both keys.
Thanks and best regards.
Have a look at the command-line program "showkey" (help: man showkey). It should answer your question.
Graphically you would need a representation of your keyboard in the "System-Settings -> Keyboard" section, which probably does not (yet) exist.
I can confirm that these buttons do not have separate functionality on a system level.
I tried the keyboard with genuine Dell app on my windows notebook for work (which was installed already) and found that only the FN-keys can have different functionality assigned to. What this did was to update the firmware of the keyboard to latest version.
So the keyboard is actually totally OK and so is KDE ;-)
Best regards and thanks to everyone invoved who tried to help.
