click: hide / click again: unhide

It's not an animated feature though. If you need that, you'd have to try using line width instead.

yes, but this can not be animated. If you want to hide a line on frame zero and then, let's suppose on frame 60, make it appear, you must use the line width tool. Select the two or more points in which the line is between and set 0 with the line width tool. Then, in frame 60, you must to use the line width tool again to make the line fatter.
This will produce the line width will getting fatter and fatter from 0 (on frame 0) to the new value (on frame 60). If you want the line start to appear after, not directly from frame 0, you must add a new keyframe between frame 0 and 60 and give it the 0 value.

Another trick I use is to make a section of the line that you want to show/hide a different shape. Then you can animate the opacity.

This seems strange. I just now finished an experiment on this very subject. I wanted the bridge of the nose to gradually appear as the head turned. I tried changing alpha channel on the intended line. For some reason I didn't understand at the time, the line would fade and the sometimes it wouldn't.

What I discovered is that I needed two noses in the same layer, one on top of the other. The nose on the bottom I could animate the alpha channel of the entire object. The nose on top didn't have the bridge lines and the alpha channel was left alone.

It seems you can animate the entire object line opacity, but specific lines within that object.

You can also overlap shapes to cover and reveal lines.
