Navigational tools

[Redroach]

Heya,
I want to get more insight into the navigation business, and I've found the navigational tools for the in-flight map, added with the last patch, come in quite handy. However, I'm still quite a bit away from developing a solid navigation strategy with these tools So I've got a couple of questions on that:
I know that you can measure distances and angles with tools 2 and 3, but I'm not quite sure how to best use the tool no. 1. With this tool, you're able to set 'waypoints' or other points of interest - but how can I use them in conjunction with the other tools? For example, if I set two waypoints, can I get a line between them, with a distance label and/or measure an angle to another line? Also, can I delete those points somehow, if I mis-clicked?
And, as stated above, has anyone developed an overall procedure to use all three tools? Maybe something like: set waypoints, get distance between them and measure angles in order to get compass bearings at each waypoint. If somebody has something along these lines, please tell me!
