I use the magnifying glass icon for the "Open quickly" window.

It's supposed to be something like Spotlight search in OS X (https://dl.dropboxusercontent.com/s/vopjz0e9tp1k1ul/2016-08-...).

The idiom is magnifying glass representing search.

The star icon more closely aligns with quick access to something used often.
