And it works on your PC? Shouldnt those be maybe as extraArgs? In the manual those keywords are not mentioned, where did you find them?

It does indeed!
I don’t think that DirectGUI widgets use extraArgs when being constructed, do they?
I honestly don’t recall–it’s been a while since I wrote this code. However, there are, I think, a few such keywords that can be inferred to exist. For example, I just tried out “popupMarker_hpr”, and it seems to work. (Use the “r” value to rotate the marker.)
Sorry, I didnt get to learning DirectGUI yet. I installed 1.10.8 and still same. Do you have latest version? Then it must be platform specific? Maybe once I get to fiddling with GUI, I might be able to help. Now, I learned that I should write comments for these keywords 
Not a problem! 
I believe that I do, yes.
Possibly, but I doubt it.
I’m more inclined to suspect that I have a modified version of DirectOptionMenu.py floating about my system somewhere–where that might be I don’t know offhand–that includes these features, and that’s being picked up invisibly.
In any case, if I recall correctly they’re not terribly useful in baseline DirectOptionMenu (as they’re lost when the menu is rebuilt), so I might just remove them and have done with it. The menu will be less pretty, but it’ll reliably work, I daresay!
Thank you for the offer!
As I said, however, I’m more and more inclined to suspect that the disconnect is coming from a modified version on my end. That’s my best guess right now!
Correction: It looks like I can get non-English characters–but I’m getting some odd inconsistencies in which characters are produced. See the following thread for more on this:
@Pignon: Could I trouble you again to try out the recent update of KeyMapper, please? While, as per the above-linked thread, I’m not sure that I’m getting the expected characters in all cases, I hope that I have the events firing correctly, now.
No problemo. You fixed it! But the game is too hard!
edit: BTW what key is the “back” key?
edit2: Im impressed you also support my “flight_stick”, the game is a bit easier on gamepad than keyboard.
Ah, excellent! 
Whew, that’s a bit of a relief! ^^;
Hah, I have heard that! XD;
Well, you have the source code, you can always adjust it. 
Aaaah… On a gamepad I think that it’s the “select” button.
Honestly, that’s more Panda’s accomplishment than mine! I just support whatever devices Panda gives me access to. But for my part in that support, thank you.
Minor update:
I’ve fixed, I believe, an issue in which KeyMapper didn’t correctly identify “wheel” events as being related to a “mouse” device.
