It is far harder to recall from memory than to recognize. It is the same with functionality of product. If you see the control that triggers a function you will immediately know that the function exists and that you can use this control to trigger it. In contrast if you use a command line or a special gesture you need to retrieve the correct command from memory without any help. This is much harder to do. | It is far harder to recall from memory than to recognize. It is the same with functionality of product.

There are many invisible functions we face everyday: Water-tabs that are triggered if you weave a hand in front of them, keyboard shortcuts and touch-gestures. As well functionality is invisible if you need to go to a certain place to see a visual representation. So the folder you save your work in is invisible as log as you don't open the file manager and navigate to your folder. Same with deeply nested menus. | There are many invisible functions we face everyday: Water-tabs that are triggered if you weave a hand in front of them, keyboard shortcuts and touch-gestures.
