The command lets you quickly search icons from Iconfinder.

The first time you run the command, you will be asked to set up some search filters. For instance, you'll be able to choose whether to include Premium icons or limit your search to Vector icons only. Once the command is configured, you can start searching the icons by typing the keywords into the Command Bar's input field.

For Vector icons, when you press ENTER the icon is pasted directly into the active app. It works great with design tools such as Figma. Pressing TAB will give you more options to choose from, e.g. open the icon page in Iconfinder or copy the URL.
