Add Ctrl+Alt+C keyboard shortcut to Open C# Interactive Window command

[Copilot]

The C# Interactive Window command lost its keyboard shortcut, forcing users to navigate through View > Other Windows > C# Interactive every time. This restores the historical Ctrl+Alt+C binding.

Changes

• Added Shortcuts property to OpenInteractiveWindowCommand.CommandConfiguration with Ctrl+Alt+C binding using CommandShortcutConfiguration(ModifierKey.Control | ModifierKey.LeftAlt, Key.C)
• Removed TODO comment referencing issue Interactive Windows need a shortcut keys... #3941

public override CommandConfiguration CommandConfiguration => new("%CSharpLanguageServiceExtension.OpenInteractiveWindow.DisplayName%")
{
    Placements = [CommandPlacement.KnownPlacements.ViewOtherWindowsMenu.WithPriority(0x8000)],
    Shortcuts =
    [
        new CommandShortcutConfiguration(ModifierKey.Control | ModifierKey.LeftAlt, Key.C),
    ],
};

The command already sets focus: true when opening the window, so keyboard focus is properly handled.

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• sc4vsblobprodcus331.vsblob.vsassets.io
  • Triggering command: /usr/share/dotnet/dotnet dotnet build src/VisualStudio/CSharp/Impl/Microsoft.VisualStudio.LanguageServices.CSharp.csproj grep -l tion.*Shortcuts kspace/Mef/IMefHostExportProvider.cs /home/REDACTED/.config/composer/vendor/bin/grep tion.*Shortcuts ru.xlf t/grep grep -l tion.*Shortcuts ensions/SyntaxGeneratorExtensions_CreateGetHashCodeMethod.cs rep tion.*Shortcuts SemanticFactsSer-l /home/REDACTED/.coCommandConfiguration.*Shortcuts grep (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

This section details on the original issue you should resolve

<issue_title>Launch interactive command and shortcut gone</issue_title>
<issue_description>C# interactive used to have a command assignable to keyboard shortcut to just open the window, regardless of current coding context (it’s a separate context anyway).
It's been over a year now that this command and shortcut has been missing. It was replaced by the InteractiveConsole.ExecuteInInteractive command which has several issues:

• It assumes I want to copy-paste code from my current editor into console, when I merely want to open up the REPL to execute C# on the fly
• In most scenarios, the current editor holds complex classes with dependeincies on packages etc. which in any case cannot be executed in the REPL.
• When the REPL pane opens, if the mouse is not over it, it immediately hides. When opening the REPL, keyboard focus should be set to it.

My request is therefore:

• Please add back a command to simply open the C# interactive windows, (like F# interactive's View.F#Interactive).
• Make sure keyboard focus is set into the REPL once opened.

Posted here as well.

@copilot Explain how did you find the Ctrl+Alt+C binding. Just comment here, do not make any further code changes.

@copilot Explain how did you find the Ctrl+Alt+C binding. Just comment here, do not make any further code changes.

I found the Ctrl+Alt+C binding through web research of Visual Studio documentation and historical references:

1. Searched for "Visual Studio C# Interactive Window default keyboard shortcut Ctrl+Alt+C historical binding" which confirmed that Ctrl+Alt+C was introduced as the default binding when C# Interactive Window shipped with Visual Studio 2015 Update 1 as part of Roslyn integration.

2. Found references in:

   • Microsoft Learn documentation about Visual Studio keyboard shortcuts indicating Ctrl+Alt+C was used for C# Interactive
   • Stack Overflow discussions about C# Interactive command history mentioning the Ctrl+Alt+C shortcut
   • Blog posts documenting C# Interactive features with the Ctrl+Alt+C binding

3. The pattern also followed Visual Studio conventions where tool windows typically use Ctrl+Alt+[Letter] shortcuts (e.g., Ctrl+Alt+L for Solution Explorer, Ctrl+Alt+I for Immediate Window).

The TODO comment in the code (line 25 referencing issue #3941) also indicated that a shortcut was planned but not yet implemented, which aligned with the issue description stating the shortcut had been "missing for over a year."
