Cleaning-up Code With Comments

I remember there was a command to add tildes to the end of a line of comments so as to distinguish it more from the actual code. I think I was using 2009b at the time and now I'm using 2007b. Was I hallucinating?

were you thinking
of multiple
lines of
comments? (curly
braces,not tildes)

To add comments into a code, simply use the percent (%) sign. For example
for i=1:10
x=i % Makes x equal to i

Control + R comments a line and Control + T removes the comment marker from the begining of a line. The comments start with the percent sign %. I have no idea in which version of Matlab these shortcuts were introduced...

Tildes mean to ignore certain return arguments:
[folder, ~, ~] = fileparts(mfilename('fullpath'))
which doesn't return anything for the base filename, or the extension. Introduced somewhat recently.
Percent symbol means the rest of the line after the percent symbol is to be considered as a comment. Can be at the start of a line of text, on the line after the code statement is done.
% This is a comment on it's own line.
magic(4) % This is a comment after a line of code.

Here is an example of some code that I previously used.
%=========================END OF SIMULATION================================
%--------------------------Root Locus Plot---------------------------------
%Details: Plots the phugoid and short period mode for the CV880M.
%Configure results window number 4
I don't remember how but for 'END OF SIMULATION' and 'Root Locus Plot' I remember that I didn't simply smash the = and - keys to get them centered. I used some other shortcut key.
