Hi thesixtyeight,

There is something a little similar to this actually built in already - if you just click normally if there are several things all within target distance (like say 3 lines radiating out from a common center point and you're clicking near the common point), the preference is to target unselected objects which will become selected. So if you click 3 times on the common point you should end up with the 3 lines selected.

If you hold down ctrl and click the preference will be reversed, it will have a preference for targeting selected objects which will then get unselected. This is only for situations where there are many different targets clustered close to each other.

Really the best way to avoid selection and deselection problems is to avoid clicking in ambiguous areas to begin with, and to use the mouse over feedback to help see what's going to happen before you click. When a curve is going to be deselected it will get a dark halo around it, when it's going to be selected it gets a bright halo around it. If you intend to select things and you see a dark halo that's an indication that you shouldn't click there, it's not going to do what you want.

Well are you only ever using boolean difference or are you using boolean union sometimes too?

Those pop out things are called "Command sets", and when you open a command set the last command that you used in it is the one that will get launched. Except that is for commands that can work without any additional stage in them such as boolean union. If boolean union did launch automatically then if you had 2 objects already selected before pushing the "Boolean" button, it would run boolean union and be all finished which wouldn't be good if you wanted to run one of the other booleans instead.

You should be able to repeat this systematically - just run boolean union and do something else like draw a line and then come back to booleans, it should open up empty just like you show but that's intentional behavior.
