NVDA now reports the result of the Word commands to expand and collapse headings.

Description of development approach

Use Word object model (if available) as done for many Word gestures, no matter if UIA is enabled or not

Test OK in French system/Word, remapping the gesture as needed, i.e. mapping alt+shift+6, which collapse a heading. Note: it has been done so, because the dash is on the same key as the 6.

But strangely, setting my Word (Office) and my keyboard layout to English, I cannot collapse a heading with alt+shift+- as documented here. Could someone with a real English Word/system confirm that this shortcut is the one to collapse a heading?

It has been tested in the Chinese version of Word. This function works normally. The Chinese version of Word has the same shortcut keys as the English version.

After further testing, I found that there seems to be a problem with this function in the Outline view of Word. Regardless of pressing Alt+Shift+Plus sign (+) or Alt+Shift+Minus sign (-), NVDA prompts Expanded, but the operation has been performed correctly.
