Shortcuts appearing when using Option+arrow in Outlook on Chrome in Mac

This issue has been identified with Outlook on the web (Outlook 365 accessed via Chrome on macOS). The behavior occurs because the web application intercepts certain macOS-native text navigation commands specifically the Option+Arrow key combinations and repurposes them within its own accessibility and keyboard shortcut framework. As a result, instead of performing the expected word-by-word navigation, the application displays access key prompts, interrupting the text editing workflow.
