If you have colours other than black that you'd rather not grayscale: - use the rectangle tool to select the text, - reduce Saturation (several tools in the Colour menu do this) until it's all some shade of grey rather than colour, - then fiddle with Brightness/Contrast until the black is an acceptable black and the white is the appropriate white to match the rest of the document. not sure if that
