Hi
I want to add the option to multiselect 1 or more entities (graphics) from my map(can be on different layers) with, for example, the alt key.
When the alt key is not pressed, normal selection is preformed (1 by 1), But when it pressed a
"multi-selection mode" is enables and now the user can drag as much entitles as he wants and they will be select.
like when you press shift, you can mark some a window and it will center and zoom to the selected window
so something like this.
Maybe is there a way to "connect" (like an event or something) to this selection and call my own function
