Code Snippet

Snip generated by codegen:

    # Fill input
    page.fill("input", "playwright")
    # Press AltGraph
    page.press("input", "AltGraph")
    # Fill input
    page.fill("input", "playwright@example.com")

Describe the bug

When typing an email address into an input, codegen creates a fill command up to the @, then inserts an AltGraph keypress, then continues with the final fill command.

IMO Codegen should try to avoid the extra commands. Without copy-paste the user will always have to use AltGr to write the @ but the browser should not receive it as a separate keypress I guess. A developer could still insert it manually if required for some special case.
