For example, if you have a TODO comment, or if you perform a search, the related lines are marked in the overview ruler; clicking the markers takes you to the corresponding line.

例如，如果有todo注释，或者如果执行搜索，概览标尺中将标记出相关行；单击标记将把您带到相应行中。

Directly to the left of the line where you want to add the breakpoint, open the marker bar (vertical ruler) pop-up menu and click Toggle breakpoint.

在要加断点的行的最左边打开标记栏(垂直标尺)弹出菜单并单击Toggle Breakpoint。

This is the ruler [with that] you can draw a straight line.

③这就是那把尺子，您可以用它划一条直线。
