How Do I Extend a Sketch line While Keeping the Same Trajectory?

I’m sure this must be a simple thing, but I haven’t figured it out yet.

Let’s say I have a sketch line, and it’s going off on an angle. If I want to then extend the line on the same exact trajectory by dragging the point at the end of the line, how do I do that? Currently, If I just click and drag it, it is free to go wherever my mouse happens to wander. If I don’t keep my hand completely steady while dragging, the angle changes as I’m dragging.

While it’s helpful to have the various sketch guides enabled, they don’t prevent the line from deviating off course.

In other software, If I hold down a key like CTRL or ALT or Shift while dragging, that keeps a sketch line from straying off trajectory as it’s being dragged– but I tried all those in Shapr and none of those keys seem to affect it. Is there a way to do this?

If you snap the first point on the end point and the second point you hover over the line you want to extend purple line will appear to let you align.

Also you can use the parallel constraint.

But would be nice to have extend sketch feature.
