How can I change multiple connectors at once in draw.io?

I created a draw.io diagram. I like to have slight changes to my connectors (change arrow styles, thickness…). I have many connectors in my diagram, so I don’t want to change them one by one. I found out that I can select them by holding down Shift, but I like to have a more convenient way of changing the connectors. Is there a way to select all connectors (or shapes) at once?

Hi there. Yes, you can select all connectors at once. Just go to Menu > Edit > Select Edges (or Select Vertices, if you like to select all of your shapes). Now you can use the Format panel to change the styling as you wish.
