restarting build at a step

[bradw2k]

Newbie question, but I'm not seeing how to just starting building at the step of my choice in the GUI. I can right-click to get the "Rebuild Selected", but that just builds that step and then stops. Or I can choose to "Start from Cursor", but if that cursor (arrow) is not where I want then that doesn't help me, and I don't know how to move the cursor manually.

My workaround has been to do both, Rebuild Selected, immediately cancel, so now the cursor is where I want, then Start from Cursor, then press Play.

Surely there is an easier way to starting building at the step of my choice?
