To comment out a large block of code in the Editor or Live Editor, select the code and on the "Editor" or "Live Editor" tab, click the "Comment" button. This inserts a "%" symbol in front of each selected line. Alternatively, select the code and type "Ctrl" + "R". To uncomment the selected text, click the "Uncomment" button or type "Ctrl" + "T".

You also can use the block comment operators "%{" and "%}". The "%{" and "%}" operators must appear alone on the lines that immediately precede and follow the block of help text. For example:

%{
   Stuff to be commented out
%}

Also, the control-r and control-t work for C source code as well ... putting and removing the // style comments.

Simply start with *... and write whatever you want. This will enable you to write a very long comment line

For example *... This is a very very long comment

Rather than comment large sections of code, I bypass them with the following syntax.

for dont_go_here = []
  % code I want to skip including all nested comments, etc. can stay here unmolested
end

This assumes that your if, for, case, try, and switch commands within that block are all terminated properly with an 'end' Otherwise the script won't parse.
