@munybt Thank you for the report. Know I understand why they were no mention to it in https://www.w3.org/TR/wai-aria-practices/#combobox! I'm stupid, I should have seen it coming. Anyway, what do you think of this diff, does it solve your problem? Do you want to submit a pull request? :)

Yes, if it fixes the problem :)
Note that it also should work when one presses SHIFT+END and other combinations that include these keys

@munybt Do you mean we have another problem? I'm on the macOS platform, I suspect you are on Windows, where the native behavior is different for the Home and End keys.

[munybt]

@oliviertassinari Yes, I am using Windows. You are right, the behaviour is different between Windows and macOS

[munybt]

@oliviertassinari Can you please explain how I can test your modification or try to fix this bug myself?

@munybt You can clone the Material UI repository and make a patch locally. I'll send a PR in a few hours, so in the next versions of the package this problem should be solved :)
