Original GitHub issue: https://github.com/debauchee/barrier/issues/1165

My setup consists on two laptops, both running Arch Linux. My keyboard (C3Tech K-W40BK) has support for 10 multimedia keys. Everything works, except for calculator key and browser key.

For example, the log contains the following when I press Calculator key while controlling the other laptop:

[2021-05-17T06:50:41] DEBUG2: mapped code=148 to keysym=0x1008ff1d
[2021-05-17T06:50:41] DEBUG2: mapped keysym=0x1008ff1d to keyID=0
[2021-05-17T06:50:41] DEBUG1: can't map keycode to key id

Analysing the source code, the keycode 148 (keysym 0x1008ff1d, named as XF86Calculator by xev) would map to s_map1008FF[0x1D] and the keycode 152 (keysym 0x1008ff5d, named as XF86Explorer by xev) would map to s_map1008FF[0x5D].

The forementioned array does not contain the correct mapping, as these positions are zeroed.

fc045fc793/src/lib/platform/XWindowsUtil.cpp (L1257) should be something like:
/* 0x18 */ kKeyWWWHome, kKeyAppMail, 0, kKeyWWWSearch, 0, kKeyAppCalculator, 0, 0,

fc045fc793/src/lib/platform/XWindowsUtil.cpp (L1265) as well should be:
/* 0x58 */ 0, 0, 0, 0, 0, kKeyAppBrowser, 0, 0,

If it's possible and, of course, compatible between all the supported OSes, could it be implemented?

Thanks in advance!
