I have a similar query... using MacOS I see the option in the PLAN menu and the keyboard shortcut is ^⌘+ BUT I'm not sure which keypress to use for "caret" the first symbol?

Hello - new here. Like the OP I'd like to say "thanks".
I'd originally drawn up all my plans in Illustrator 15+ years ago... now I'm making some changes and tried Sketchup - felt gutted.
Sweethome is a delight. THANK YOU.
