Rotating the Map
- Rotate with LMB: By holding SHIFT + ALT and using the LMB, the user can rotate the map as needed. Note that rotations made with this key combination are not saved in the project.
Selecting Multiple Objects
- Selecting with CTRL: By holding the CTRL key, the user can select multiple objects on the map at the same time, provided that the object selection interaction is active.
