great questions!
ok, the icons when pressed will mostly bring you to another screen on the touch screen, so like if i were to click the inventory (the first icon) it would change the bottem screen (except the icons which are always there) to the inventory menu, it will also pause the game.
but pressing the sword will equip the sword (or whatever weapon in that slot) tbc↓↓↓
