On macOS, I commonly use the `command``left arrow` or `command``right arrow` shortcuts to move the cursor to the start or end of text. 

Unfortunately, if I do this in Chrome desktop web browser app, and the keyboard focus accidentally escapes whatever text field, then the browser will navigate forward or backward in history. 

I only expect `command``[` or `command``]` keyboard shortcuts to navigate history. 

What's the simplest (preferably avoiding third-party apps) way to do this (something in `chrome://`, perhaps)?
