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?

To add comments into a code, simply use the percent (%) sign. For example
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.
