Shortcut for GitHub Copilot's #selection Inspired by Cursor's Ctrl+L

Cursor's Ctrl+L was so convenient that I made it possible to execute GitHub Copilot's #selection with a command. The final behavior looks like this ↓

How to Make Selected Text in the Editor the Chat Context (Default)

GitHub Copilot

Select the text, then type #selection in the Chat, and the selected text will be added to the context.

Cursor

Cursor provides a shortcut to add selected text to the context.
Press Ctrl+L to add the selected text to the context.

Cursor is super convenient!! So I made it possible to execute the same action with a shortcut key in GitHub Copilot.

Execute GitHub Copilot's #selection with a Command

After selecting text in the editor, right-click to see the menu item Copilot > Add Selection to Chat. This means the action "Add selection to Chat" is registered as a command.

If it's registered as a command, it's simple. Open the GitHub Copilot Chat extension, click the gear icon, and open Keyboard Shortcuts.

Next, search for Add Selection to Chat and set a shortcut key.
Press the + button, then press any key to register it as a shortcut (the image shows the key pressed for the screenshot).

Since Ctrl+L is a default VS Code shortcut, I set it to Ctrl+L Ctrl+S.

After changing the shortcut key, the Source changes from the GitHub Copilot Chat extension's shortcut to User, so be careful when checking the settings again. You can find it by searching for User in the shortcut key settings list.
You can also reset it to the original state by right-clicking.

With this setup, select text in the editor and press Ctrl+L Ctrl+S, and the selected text will be added to the Chat context. Super easy!

Summary

This can be applied to all commands registered by extensions on VS Code, so you can set shortcut keys for other extensions in the same way.

If you find yourself thinking, "I wish I could execute this operation in VS Code with a shortcut key," try looking for the command and setting a shortcut key in the same way!

Have a great VS Code life!
