我刚买了一台 Logitech Spotlight Presenter,它有两个按钮,其关键代码与我的演示文稿 (revealjs) 不兼容。
Next
和Previous
绑定为Right
和Left
,而我想将它们更改为n
和p
。我正在使用 Ubuntu 18.04 和 ArchLinux。

以下是当前的显示键:
# showkeys --scancodes
0xe0 0x4d 0xe0 0xcd
0xe0 0x4b 0xe0 0xcb
# showkeys --keycodes
keycode 106 release
keycode 105 release
以下是根据我的键盘显示的键:
# showkeys --scancodes
0x31 0xb1
p0x19 0x99
# showkeys --keycodes
keycode 49 release
keycode 25 release
我推断出以下内容/lib/udev/hwdb.d/61-logitech-spotlight-presenter-revealjs.hwdb
:
# This file has been created to improve Logitech Spotlight Presenter in revealjs
evdev:input:b*v046dpc53e*
KEYBOARD_KEY_69=p
KEYBOARD_KEY_6a=n
然后我尝试了以下方法
$ sudo systemd-hwdb update
$ udevadm trigger
$ sudo udevadm control --reload-rules && udevadm trigger
但我的遥控器仍然会触发Right
/ Left
。
