Description Michael Roe 2019-10-04 21:13:15 UTC
The mappings for keyboard scancodes on Linux do not include keypad left and right parentheses (used on some Microsoft keyboard), keypad plus/minus, LANG1 and LANG2 (used on Korean keyboards), XK86MenuKB, and F20 (remapped to Audio Mic Mute in the usual X11 config).

Here's a patch to fix it.
