For my laptop that ships with Windows, I have figured out that upper row "Cast" button merely simulates "Super+P" (and a couple of neighboring buttons act the same), therefore the binding fix for sway was just:
bindsym $mod+p exec ...
There is also a button that depicts a designer's faultsome non-associative symbol (probably assistant or AI) that is recognized as Super+Shift+XF86Assistant by wev. It would be perfectly ok, but wev appears to be the only program to catch this "XF86Assistant" part -- sway takes it as Super+Shift, and Emacs as s-<0x10081247>. Setting it to something or remapping Super+Shift would apparently turn WM experience into a quest.

Is there anything I can do? The piece of engineering takes the legitimate place of right ctrl.

Do you use emacs or https://archlinux.org/packages/?name=emacs-wayland ?
How do you assess the sway-itself behavior?
The limitation is probably on xwayland.
You're not getting out of the keyboard generating a combo but maybe can https://wiki.archlinux.org/title/Map_sc … o_keycodes or https://wiki.archlinux.org/title/Input_remap_utilities to map it away from XF86Assistant into eg XF86Search, https://bugzilla.redhat.com/show_bug.cgi?id=1615700

I use emacs-wayland from the 'Extra' repo.
Sway doesn't respond to this key alone, but using it as Super+Shift works (e.g., {this key}+Q closes focused window).
Some of my apps require xwayland, so disabling it is not my case.
Thanks for the links! I was trying udev, but realized that setkeycodes works to remap XF86Assistant. https://wiki.archlinux.org/title/Map_sc … etkeycodes

Could you specify how exactly you managed to remap XF86Assistant? I'm struggling.
Thanks!

Hello!
Obtain a -> Hex Scancode <- of a problematic key with evtest (to the right of MSC_SCAN, see section 1.1 of https://wiki.archlinux.org/title/Keyboa … _scancodes). Notice that keyboard will give you a combo, but you need to look for the Scancode of XF86Assistant only. In my case it was 6e.
The same way, obtain a -> Decimal Keycode <- of the desired key (to the left of KEY_{KEYNAME}, see the same section). The new combo will be $mod+Shift+{desired_key}, thus avoid remapping to existing bindings.
Remap with (afaik a built-in program)
# setkeycodes scancode keycode
https://wiki.archlinux.org/title/Map_sc … etkeycodes
You can see by these links that there are other ways to remap, this is just how I did it.

Hi,
thank you!
I used showkey to figure out the code but it was wrong (the wiki warns about this but I didn't see it). evtest did report the correct one.
For me it was:
# setkeycodes 6e 16
Keycode should be subtracted by 8 to get the right key (25, Q, is 16 for setkeycodes on my device).
