    You don't want to use waitforbuttonpress since it locks the figure gui (no zooming, panning etc).

    pause can cause the command window to steal the focus from the figure.

    figure('KeyPressFcn',@(obj,evt) 0);
    

    and then wait for CurrentCharacter property change:

    waitfor(gcf,'CurrentCharacter');
    curChar=uint8(get(gcf,'CurrentCharacter'));
