Simple select tool feature I can't figure out

When selecting lines in a drawing, to add to the selection you hold shift. What do you hold to remove a line? So if I grabbed a couple extras and don’t want to re-select the whole thing, how can I remove the strays? Often it’s alt-select or option-select, but neither of these do it on AP3.


Thanks, that works. I’m just going to take this pencil out of my eye and go on my way…

Hold-Shift then clicking on the line you want to deselect works for me.
