How to continue an orthogonal line as opposed to moving the last segment?

[bsferrazza]

I primarily use drawio for circuit diagrams where I need orthogonal lines that bend multiple times (and not have just a single right angle). You can accomplish this, but I haven't figured out a convenient or reliable way to do so. After you make a right angle and wish to draw a new segment orthogonal to the last segment, if you attempt to continue to draw from the current endpoint, it will instead move the last segment. Is there a keyboard shortcut to override this behavior and instead continue the line?

The only way I've found that I can do this is to first grab the middle waypoint of the last segment and move it a little and then back. Only then does it allow me to grab the endpoint of the last segment to create a new segment that's orthogonal to it. Obviously that's clunky, tedious, and prone to altering the shape I really want. I figured there would be some key I could hold, such as CTRL, as I pull from the last segment's endpoint to begin a new segment orthogonal to it.

I've attached an image that shows the sequence I described above and copied and pasted screen grabs of each into a single composite image. Thanks for your help!
