feat: support `Backquote` key

[melMass]

Hi,

I'm trying to debug the proper keycode for the key at the left of the 1 in the top row of an azerty keyboard. I tried Backslash (this is mapped to ><), Backquote (this is mapped to the proper backquote on azerty), and a few others that failed to register altogether. Is there a way to register all supported keycodes in order to debug that?

Thanks for the lib really useful and it also integrates well with slint-ui

There is a lot of keys that we don't support out of the box and hopefully we can add gradually.

I did some research and found the keys that we need to use: Windows: VK_OEM_3 https://learn.microsoft.com/en-us/windows/win32/inputdev/virtual-key-codes Linux (X11): XK_quoteleft https://docs.rs/x11-dl/latest/x11_dl/keysym/constant.XK_quoteleft.html

@pewsheen can you check what is the code for Backquote on macOS?

Should be kVK_ANSI_Grave (0x32)

Looks like we already support this key on Windows and macOS, what platform did you test this on? or does it work on some layouts while others don't?

• I tried on an AZERTY Mac keyboard but I can check on an AZERTY windows in a few (there it's the ˋ²ˋ key on AZERTY)

• French layouts

I see, I think that's the expected behavior when you change layout. Windows also behaves this way, so I will go ahead and add the key to Linux as well and then I will mark this issue as solved.
