By default, both the Numpad Insert key and the Extended Insert key are set as NVDA modifier keys, but users can designate the Caps Lock key as an additional NVDA modifier key. Note: Some keyboard shortcuts require using the NVDA modifier key. NVDA also has decent support for Internet Explorer, but the best testing combinations are NVDA + Firefox, NVDA + Chrome, and NVDA + Edge. NVDA works well with Firefox, Chrome, and Edge.
