button = waitforbuttonpress
if button == rightMouse
methodOne
elseif button == leftMouse
methodTwo
else
break
end

It will not work. You cannot exit from loop this way. You only can start loop as one of the methods, However, if you start loop[ you will not be able to stop evaluation by mouse click because decision is outside the loop.

f = figure(1);
click_type=get(f,'SelectionType');
if strcmp(click_type,'normal') %right click
%Do some stuff
elseif strcmp(click_type,'alt') %left click
%Do some other stuff
end

Ok, this looks like the sort of thing I need. Can you tell me if I need to use the figure as a reference? I.E does the click always have to be on that figure? Can I use some sort of general:
button = ButtonDown
instead?
Also, Will the code pause on the click_type statement or do I write:
f = figure(1);
waitforbuttonpress
click_type = get(f,'SelectionType');
??

As far as I know, the click needs to be in the figure axes.
