If you're working on a big canvas, you may need to make part of your genially closer or further away to be able to place elements with more detail.  To do this, you'd need to use the zoom function available in the Editor.

To do so:

1. In the Editor, find the buttons to zoom (+ or -), located in the lower center zone.

2. Click on the button "+" or "-" according to whether you need to bring the canvas closer or take it further away from you.
