Default keybinding for focus next/prev vessel on QWERTZ keyboards
The default keybinding for focussing the next/prev vessel is [ and ], which is fine for QWERTY keyboard, which are used in most english speaking countries, as they are single keys. However, a big part of the playerbase does not live in english speaking countries and therefore may not have an QWERTY keyboard.
The keyboard in the attached picture uses a QWERTZ layout, which is for example widely used in germany. In order to access "[" or "]" you have to press "AltGr" (next to the spacebar) followed by 8 or 9. This may cause some trouble, as "AltGr" is right next to the spacebar. It is possible to change the keybinding, but due to the high number of keybindings KSP already has, it might take several minutes to find it.
Note: Its also much easier, to use a single key to switch vessels. I use PageUp and PageDown (labeled as "Bild" in the picture) to switch vessels, as these keys dont seem to be used otherwise.
Just a minor inconvenience, but i would really much appreciate a change there.
