Hello MATLAB users,
Could you please let me know how I can find the proper codes for each key in the keyboard and mouse and then use it in my script?
Suppose a user needs to press either "f","m" or "left mouse button" before importing female, male or children's name, respectively.
Thanks for your help :)

You don't want the actual keycodes; MATLAB will decode them for you. See the code example at
Mouse buttons do not create key codes, and are not registered by getkey() or by KeyPressFcn or WindowKeyPressFcn callbacks: you need ButtonDownFcn or WindowButtonDownFcn instead, and then you look at the figure SelectionType property to figure out which mouse button was pressed (there is no explicit "left mouse", "right mouse", and so on, just single mouse event with "modifiers")
