Summary: Missing X11 to keycode mappings
Product: SDL Reporter: Michael Roe <mroe149227>
Component: eventsAssignee: Sam Lantinga <slouken>
Status: NEW --- QA Contact: Sam Lantinga <slouken>
Severity: normal    
Priority: P2    
Version: 2.0.8

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:
