Probably a regression, will check it out later today.

[Bios-Marcel]

Mind telling me which terminal emulator exactly you use? Oh and can I get your shortcuts.json please?

xterm version 351 with vt340 option

[Bios-Marcel]

The man page doesn't mention how to enable vt340 mode. Mind helping me out? I don't really use xterm.

[SirCipherz]

xterm -ti vt340

[Bios-Marcel]

Using the same shortcut as you and the same terminal+args, it works fine for me. What commit are you on?

[Bios-Marcel]

Hm, I am sorry, but as I can't reproduce it, can you look into it?

[SirCipherz]

I'll

So, I checked with another keyboard what was the backspace key ID it was "7002a" and on my laptop it was "0e"

[Bios-Marcel]

What's more interesting, is the output that tools/keyevents/main.go gives for each of the keys on both machines.
I don't really know what "7002a" is supposed to mean.

So, I checked with another keyboard what was the backspace key ID it was "7002a" and on my laptop it was "0e"

0x07 is the code for Keyboard page in USB HID Usage Codes and 0x2A is the HID Usage ID for backspace. They are sometime written together as 0x0007002A.
0x0E is the "XT" ("set 1") scancodes for backspace.
