Hi, how do I present an information in a figure window that tells the user that a sequence of words will appear and also tells the user to press any key? After pressing any key, the program should go to a different figure window.

The question is far to general to be answered efficiently. Please post, what you have tried so far and ask a specific question describing, what does not work as expected.

While "go to a different figure window" is clear to you, it is not for the readers.

It looks like you want to focus on a second figure window when user presses a key on the first one. Try using the "WindowKeyPressFcn" callback function as in the code below:

 fig1 = figure;
 h1 = uicontrol(fig1,'Style', 'text', 'String',...
 'Welcome!!Press any key....',... %replace something with the text you want
     'Units','normalized','Position', [0.5 0.5 0.1 0.1]); 
fig1.WindowKeyPressFcn = @press_func;
function press_func(src,event)
    disp('key was pressed');
    fig2 = figure;
      h2 =  uicontrol(fig2,'Style', 'text','String', 'New fig','Units','normalized',...
          'Position', [0.5 0.5 0.1 0.1]); 
      %switching Visible property to ON brings focus to fig2
      if fig2.Visible=='on'
          fig2.Visible='off';
      end
      fig2.Visible='on';
end
