研究方向

First, understand the request by reviewing the linked VS Code issue (microsoft/vscode#127764) for the expected behavior. Then examine the xterm.js source to see how terminal options are defined and used, likely in the OptionsService or related files. Look for existing Mac specific options or keybinding handling to model the implementation. No existing PRs or comments provide further direction, so the implementation should be straightforward: add a new option 'macOptionIsEscape' and handle the option key mapping accordingly.
