Does anyone know how to open a List box pop-up pop-up menu. This is a drop-down menu where you type in some value & a load of options (versions of what you typed) open up: typically a search box. Visually there's a little arrow next to the edit box, & a sighted person will just click or hover-over that arrow, then slide down the list to the value they want. Typically this appears in Safari, e.g. in a search on twitter; but I've also seen it as the date picker in Zoom. According to Apple's own documentation you can activate a List box pop-up pop-up menu with VO+space or with quick-nav using the arrow keys. Neither works. It's driving me mad.
