Tested and works with Factorio 0.17, 1.0, and 1.1. Note that only chests and logistic chests are considered for the item search, items inside of other inventories such as cars, trains, corpses, etc will not be found. Tested and is compatible with mods that add new assemblers and chest types. Clicking the button repeatedly will cycle through all machines/chests containing the selected recipe or item. Clicking the buttons to the right of the filters will place a flashing arrow above machines producing the recipe in question, or chests containing the item (or focus on the machine if in map mode).
Pressing the hotkey (ctrl+w by default) will bring up a window allowing you to select a recipe and/or item to search for. Ever wondered where an item is being produced in your mall, or where it's being stored in your logistic network? Wonder no longer.
