An 8 x 10 hand -dawn b & w map needs place names of cities and town. The map has been saved. When I type in a city name and then go to another location to type in another city name, then see a typographical error in the first city name, I cannot go back to the first city name and make changes. Is there a way to return to the original line of type (city name) and position the cursor at the front of the name and correct the error?
