Mark Pearson fae6f9589d Input: atkbd - map F23 key to support default copilot shortcut
commit 907bc9268a upstream.

Microsoft defined Meta+Shift+F23 as the Copilot shortcut instead of a
dedicated keycode, and multiple vendors have their keyboards emit this
sequence in response to users pressing a dedicated "Copilot" key.
Unfortunately the default keymap table in atkbd does not map scancode
0x6e (F23) and so the key combination does not work even if userspace
is ready to handle it.

Because this behavior is common between multiple vendors and the
scancode is currently unused map 0x6e to keycode 193 (KEY_F23) so that
key sequence is generated properly.

MS documentation for the scan code:
https://learn.microsoft.com/en-us/windows/win32/inputdev/about-keyboard-input#scan-codes
Confirmed on Lenovo, HP and Dell machines by Canonical.
Tested on Lenovo T14s G6 AMD.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
