Using the Alt + F7 shortcut key will take you to the first mistake in the sentence where the insertion point is currently located or, if nothing is tagged in the current sentence, to the next error.
It will open the spelling and grammar shortcut menu (the same one you would get if you right-clicked on the questionable entry). You must make a selection from the shortcut menu before you use the shortcut key again. If you do not wish to make any alterations, position the mouse in the next sentence and then use the shortcut key to take you to the next error.
