Description Michael Roe 2018-05-11 18:51:48 UTC 
The mapping from X11 scancodes to SDL scancodes in events/scancodes_xfree86.h is missing entries for the additional keys found on some numeric keypads, such as the Microsoft Natural 4000. The effect of this bug is that these keys won't work in SDL2 applications.

Here's a patch to fix the issue. (The patch also fixes another bug, that the scancode for the Fast Forward key was wrong).
