"Close" all loops in a script m file

I have multiple for loop

for a=1
  test
end

for b=1
test
end

In an editor I can "close" the loops with (+) and (-). Is there any way to close all loops in a script file?

What's the condition to close the loops?

Yes, it is possible to fold all loops in a file. See the "Code Folding" section on this documentation page for more information.
