Hello, I am training up on some of my company's parts and doing so by stepping feature by feature through the individual components. Unfortunately in this case the component was designed by our China team and much of it is written in Chinese. I came across this double-box icon as I am stepping my way through and do not see a matching icon anywhere on the 'Features" ribbon. (see below)

My question in this instance is what does this icon represent? And for future reference is there a good method for identifying features in reverse by their icon or some other method?

Thank you,

Reid
