To split a way, select the point at which you want to cut, and click the Scissor tool or press X on your keyboard. Hint: Add a node first in order to cut between nodes. To make a junction between two ways, draw as usual until you need to make a junction. Then as you move your mouse over another way, the points will light up blue. Click on one of the blue points or any other desired location on the way to make a junction. To disconnect a junction, select the point on the way you wish to alter. Then press - on your keyboard to remove the point. To reverse the direction of a way, click the Reverse Direction button in the bottom right corner. The direction of a way is only a concern for those features with a "oneway" tag - oneway streets, coastlines, islands, and so on. To create a way running parallel, select the way and click the Create Parallel Way button in the bottom right corner or press P on your keyboard. To create a way that shares nodes with an existing way, start drawing, click the first two shared nodes, then press F to automatically follow the existing way.
