Question: Presentation results

Hello,

Just a question about presentation.

If I have  a program like this:

for i to N do
for j to N do
i+j
od;
od;

How to show it like this?

for i to N do
   for j to N do
        i+j
    od;
od;

I have tryed some compositions with the keyboard but "everything doen't work".

Many thanks,
Ternox
