This is a powerful processing tool that will save you unnecessary typing time. For certain natural food such as apples and oranges, the individual food size can vary significantly; by activating the "Resize" tool, you can make the food larger or smaller (for most food). To do this, simply click on the food and hold the left-mouse button down, now drag the mouse to the upper-left hand corner to enlarge the food, or drag it towards the bottom-right to make it smaller. A temporary display box will show interactively the changes in its weight.
For liquids in a glass, cup or can, a vertical meter appears with a red arrow pointing at it. This arrow corresponds to the level of its content. By dragging the red arrow down or up, the display will reflect its current volume; let go of the mouse button will set the value and the image will be changed to simulate proper reduction or augmentation.
