Description Michael Roe 2018-05-11 18:42:07 UTC 
The mapping from X11 keysyms to SDL keycodes in src/video/x11/SDL_x11keyboard.c is missing entries for the multimedia keys found on some keyboards, such as the Microsoft Natural 4000.

The consequence is that these keys don't work in SDL2 applications that needs
a keycode to keysym mapping.

The following patch will fix the issue:

--- SDL_x11keyboard.c   2018-05-11 19:36:07.443282000 +0100
