Recently, I was trying to figure out how many miles it was from a highway exit to the intersection of the road leading to my house. Some family friends were coming to visit and I wanted to give them an idea of how far they would have to drive before they had to keep an eye out for the tricky turnoff to my neighborhood. But without specific addresses to punch into Google Maps, I wasn’t sure how to plot the path from point A to point B.
This led me to right-clicking (or control-clicking on a one-button mouse) on the Google Map of my area and, lo and behold, up popped a contextual menu containing the command Directions from here. Selecting that placed an A marker on the map which I could freely drag around, so I placed it on the exit ramp of the highway. Then I right-clicked again near the ramp for the road where my friends would have to turn off and chose Directions to here, placing a B marker on the map, which I could again drag to a specific location. And just like that, I had the information that it was 5.3 miles to my exit—all without having a specific address for either the starting or ending points.
