Found what looks like an #NVDA bug, or possibly #notepad++ bug. An & followed by a space will read a fake command key suggestion when changing focus to the notepad++ window.

NVDA: 2025.3.2.
Notepad++: 8.8.8.

Minimum reproduction:

Open notepad++, if a file is open use ctrl-n for new.
Type the following string in the file: "& ".
Alt-tab in and out. On the focus, NVDA will announce "alt+space".

I just wanted to read before bed.
