Ok... on the one hand we have the CTRL/ALT/Anything-Left and CTRL/ALT/Anything-Right problem and it's not perfect, but we have a solution...
But it seems that I have a lot of problems more with the German keyboard for which I did't find a solution yet....
Background knowledge:
On the German keyboard it makes a difference if you enter a key on the main keyboard, or if you type the same on the numpad.... (I don't know if other languages have the same problem....)
For example: " * " on the main-keyboard is detected with entering by numpad with " Numpad * "....
The next thing is, that the " + ", " ~ " and the " * " signs are placed on the same button on the German keyboard.
You have to press the "shift" button to reach the " * " -input on the key that includes " * " and " + " and " ~ ".....
Problem:
If you want to configure an input for DCS World that takes for example CTRL-left + * it takes additionally the shift-button to do this....
And as expected Streamdeck will not take this...
I tried it another way with "Caps Lock"
That works good! At first glance....
Streamdeck takes (even with Caps Lock) the CTRL-input and then it automatically takes the " * "-key together to a combination.
So actually in you Streamdeck control-surface you can see "CTRL+*"
BUT:
When you deactivate Caps Lock later, it doesn't only remove the function from the keyboard, it also changes the saved configuration on the Streamdeck back to the non-caps lock key " + ".....
Another Problem:
Keyboard-keys on the English keyboard layout and keyboard-keys on the German keyboard layout are differently assigned.....
So where we have the button "ö" (=combination of o+e) the english keyboard has the ";" (=semicolon).....
And where the German layout has the ";" and the "," on the same button, the English layout has the "," and the "<" ......
Confusing.....! -.-
So maybe I can set aaaaaaall the key combinations on streamdeck with the english layout (what forces me to find out which english button lays behind the german button layout on the whole keyboard), but later when I switch back to german-layout, half of the combinations won't work any longer, because the input is often NOT identical between English and German layout.....
That's all f*** up... and it is way to complicated and way too much effort to configure Streamdeck....
Reset aaaaaaaaaaaaaaaaaall the key-combinations in DCS-World to a german layout seems also to be completly insane....
------->>>
In the end I had the idea to use the Streamdeck identical as a gamepad or joystick or another periphery that brings it's own buttons....
Idea:
Instead of setting a key in the Streamdeck control-surface, you configure a key in DCS and simply press the Streamdeck-button....
DCS could recognize it as "STREAMDECK_INPUT_01" up to "STREAMDECK_INPUT_32" (or something like that....)!
Of course this is not a perfect plan, because you have an unlimited sub-layers on Streamdeck that can be configured....
But it seems to be way easier than all the other options so far and you would still be able to rename a Streamdeck button and also to depoosit a picture....
The only question is:
How can I turn my Streamdeck into a controller like the Logitech/Saitek Farming Side Panel?!
Google delivered no solutions so far....
Maybe someone in this community has an epic idea how to do it?
(Yes, I know, there is a lot of useful hardware simulator-stuff from Thrustmaster and so on...
But Streamdeck costs a lot and I bought it for exactly these kind of application and I really like these funny coloured buttons with text....
Especially when I can press them and something moves!)
