Once upon a time, using fonts to house a library of icons to display on webpages is still a thing - we had not figured out SVG icon libraries yet.
Material Icons created by Google’s design team was very well designed. However, in the official Material Icon search, I could only search by icon name. So if I didn't know the magnifier icon was named as "search", and I typed in "magnifier", it wouldn't return anything. Also, from their list, I could not copy-paste the icon to use in my mockups.
I created this cheatsheet so that I can easily copy paste the icons in drawing programs such as Sketch, Photoshop, Illustrator... etc. To improve the filtering, I tagged the icons with keywords, so that you don't have to remember the exact name to find the icon you want.
