Multimedia keyboard generates incorrect |code| for Numpad Backspace key. |
||||
Issue descriptionOS: Linux (I haven't tested Windows/Mac) Chrome 54 Microsoft Multimedia keyboard, the Numpad Backspace key generates the wrong |code| value. If generates "Backspace" (the same as the normal Backspace key) instead of"NumpadBackspace". This bug means that 2 keys on the keyboard produce the same |code| value so they cannot be distinguished. The |key| value for these 2 keys is correct: they both produce "Backspace". You can test these values by visiting: https://cdn.rawgit.com/w3c/uievents/gh-pages/tools/key-event-viewer.html

garykac@ does this work on FireFox? I don't see a relevant scancode from evdev. So this value is assigned to be zero in the lookup table.

garykac@ do you have any cycles to give this a try? I don't have one of these keyboards available but I could try to source one. kpschoedel@ do you know what the evdev code is?

#3 According to ui/events/keycodes/dom/keycode_converter_data.inc the Linux kernel (as of 4.2) does not distinguish the two.

Confirmed this is still the case in tip-of-tree Linux https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/drivers/hid/usbhid/usbkbd.c?id=refs/tags/v4.9-rc7 If upstream ever changes, changing Chrome would be trivial. Otherwise, I don't think there's anything we can do.

Closing as there is nothing we can do. |
