I have 7 separate heatmaps representing 7 years of data, all styled the same in QGIS. The shapes of the heatmaps change slightly between the different years and it would be nice to quickly toggle 2016 off and immediately view 2015 without having to take my eyes off the map canvas to click the little boxes in the layers panel.
I could just take a print screen of each layer and paste them into something like powerpoint and use my arrow keys to have the same effect. Is there a faster approach?
