It is very easy, you have two possibilities. Either you drag the mouse over the blocks you want to select. All the blocks located underneath the translucent blue rectangle will be selected.
Or you can select your blocks one by one for more precision by holding the CTRL key down. The selectionable blocks are highlighted as soon as you press the CTRL key.
Here again, you have two options. You can either deselect your blocks one by one by clicking on them while holding the CTRL key down, or uncheck them in the blue panel on the left of your screen.
Once your blocks are selected, you’ll be able to move them easily with your mouse. You’ll also have the possibility to move them while pushing the blocks located below, to move them to another page, to delete them or to duplicate them using the bottom toolbar in the blue panel on the left of your screen.
