In PowerPoint, it is really easy to remove a background of a raster image when the background is a solid color. You just have to go to "Format > Color > Set Transparent Color". This, in my opinion, is really handy since I don't always have time for a clipping mask. I also find it sometimes more tidy.
Is there any way you could do this in Adobe Illustrator? I tried "Edit > Edit Color", but there was no option to change a solid color to none.
