Important: if you are using NVDA 2017.3 or later on Windows 10, please consider using built-in Windows 10 OCR.

To perform OCR, move to the object in question using object navigation and press NVDA+r. You can set the OCR recognition language by going to the NVDA settings panel and selecting OCR settings. The keyboard shortcut can be reassigned from NVDA input gestures dialog in the "Miscellaneous" category.
