I am studying mathematics and I find the Preview.app's freehand tool extremely useful to help me understand the documents I am reading. As you can see in the picture below I end up having a LOT of shapes to make sense of the maths. Sometimes I just need to move a group of shapes to make some space to add new ones. At present after clicking on the first shape to select it, I have to click on each further shape very carefully while keeping the shift button pressed to add them to the selection, and if I ever misclick (which happens 1/3 of the attempts) this then leads to all the selected elements being lost, requiring me to then start from the beginning. [Update: clicking ⌘Z after such an error recovers the selection up to the error!]
Is there a way to select a number of shapes in one go? That would be tremendously helpful.
I have found that if I select one shape, and click ⌘A (Edit->Seclect All) then I can select all the shapes in the page. But that does not help, as I have too many.
I have placed my edited version of the document online, so that anyone who wants can get a feel as to why clicking on individual objects is problematic and to test any solution they come up with.
