Implementation:Microsoft Playwright MacEditingCommands

Overview

MacEditingCommands defines a mapping from keyboard shortcuts to macOS editing commands, used by the WebKit input implementation to translate key combinations into native editing actions.

Description

This module exports a single constant object macEditingCommands that maps keyboard shortcut strings (e.g., 'Control+KeyA') to macOS NSResponder editing command selectors (e.g., 'moveToBeginningOfParagraph:'). The mapping covers standard editing commands including cursor movement, text selection, deletion, clipboard operations, and text formatting.

Key categories include:

Basic navigation: arrow keys, home/end, page up/down
Shift+key combinations for selection modification
Control+key combinations for paragraph-level editing
Meta (Command) key combinations for document-level operations and clipboard
Combined modifier shortcuts

Usage

Referenced by the WebKit keyboard input implementation to determine which editing commands to send along with key events on macOS.
