Hello,
About a year ago Vojta has brought up some quirks with access to menus in spacefm. At that time there was an issue with menu loosing keyboard navigation when inwoked by pressing the F10 key.
Yesterday after launching spacefm after a few months I have found something somewhere has changed and when for example pressing alt+f for the file menu I can only hear first menu item being focused. When pressing up and down arrow key the focus changes in the enu bar however orca is not reporting the changes.
This is with gtk2 build of spacefm. I am afraid this similar to what we were experiencing in Eclipse.
