It is in the list but greyed out on Ubuntu 22.04 + GNOME 42.9 with:

Version: 24.8.0.0.alpha0+ (X86_64) / LibreOffice Community
Build ID: 0dcaff6043e1f24ce0fa354dff80a86e40622247
CPU threads: 8; OS: Linux 6.5; UI render: default; VCL: gtk3
Locale: en-AU (en_AU.UTF-8); UI: en-US
Calc: CL threaded

Same with gen and kf5 VCL plugins.

Is the issue that there is no description for what it does, Cor?

Buovjaga might be able to help as he had a closer look recently with e1c59fd539222973410dc6adcb8eac4abeeb9e6a.

Yeah, there it is in the help page Cor linked:
Press Ctrl+F6 to switch to the document.

and what I documented in the code:
Set focus to the document canvas/data source

So disabling is working as expected.

Cor: what is your problem exactly? You are not even seeing the shortcut, as disabled? If so, which operating system / VCL UI are you using?

I would expect that Ctrl+F6 is listed with its function in the Customize dialog.
For me it is not: neither for the option LibreOffice, nor for the option Writer (active module)

Sorry, for me it's still unclear. Do you see the shortcut greyed out as in my attachment, or is it not listed at all?

In the shortcut, one can see Ctrl+F4 is labelled even though it is greyed out, but Ctrl+F6 isn't labelled. This definitely needs fixing. Just unsure if Cor's issue is that Ctrl+F6 _isn't listed at all_.

Sorry that you had to ask again :)
It is greyed out as in your example.

Ok, then it is working as intended as it's a reserved shortcut.

Or is this a feature request that reserved shortcuts should display their associations? That does sound useful, but I imagine would need quite a bit of coding to pull off.

I think that would be ideal.
What's the technical difference between Ctrl + F4 and Ctrl + F6 in the screenshot?

I don't see such a label for Ctrl + F4, interesting.

Even with scope changed from Writer to LibreOffice? I picked that one on purpose to show that some greyed-out shortcuts _do_ have a label.

If I change the scope I can see it.

The difference seems to be that officecfg/registry/data/org/openoffice/Office/Accelerators.xcu has

<node oor:name="F4_MOD1" oor:op="replace">
  <prop oor:name="Command">
    <value xml:lang="x-no-translate">L10N SHORTCUTS - NO TRANSLATE</value>
    <value xml:lang="en-US">.uno:CloseDoc</value>
  </prop>
</node>

Under
<node oor:name="SecondaryKeys">
  <node oor:name="Global">

and under

<node oor:name="Modules">
  <node oor:name="com.sun.star.frame.StartModule" oor:op="replace">

and

<node oor:name="com.sun.star.chart2.ChartDocument" oor:op="replace">

while the other reserved ones are missing from the file.

Indeed, if I add this under SecondaryKeys, Global:

<node oor:name="F1" oor:op="replace">
  <prop oor:name="Command">
    <value xml:lang="x-no-translate">L10N SHORTCUTS - NO TRANSLATE</value>
    <value xml:lang="en-US">.uno:HelpIndex</value>
  </prop>
</node>

I can see the Help label when in Customize/Keyboard/LibreOffice context.

Now how to find out all the .uno commands for the rest of the missing shortcuts?

thanks Ilamiri & Stéphane for moving in this direction :)

One last note: for some of these shortcuts it will be tricky to conjure up a label because they don't have a .uno command, but special handling. See bug 160462 comment 6.
