Alt + H not working for text entering?

I have not been able to get the hint (question mark box) to work using a keyboard. I have tried in Windows 10, Windows 11, on Edge, Chrome, and Firefox.

It would be great if we could get a shortcut working that doesn’t require the use of a mouse! Alt + H is supposed to do this, but it does nothing in Chrome and Edge, and opens up a help menu in Firefox.

This has been a problem for me when transcribing. I suspect it might be an issue in Clozemaster because when I mapped Alt + H to one of my mouse buttons, it still doesn’t work.

Thanks to anyone for help or workarounds!
