@Kelvin, Yes. On windows Ctrl+. and Shift+Ctrl+. will fold/unfold the code segement. Ctrl+R and Ctrl+T will comment/uncomment code on windows. To find out what had a keyboard shortcut or create one for an action, check out File -> Preferences -> Keyboard -> Shortcuts. This also an excellent type of question for MATLAB Answers

Hi everyone,

Is there a hotkey (shortcut) for collapsing and expanding code cells, so I wouldn’t need to manually click the tiny +/- sign?

Also, is there a way to quickly comment/uncomment code cells?

Thank you in advance!

Thanks Mike, I’m downloading R2009b as we speak!

Alexander,

Only functions were foldable in R2007b. Code folding for cells was added in R2008a.

Hi, Alexander here again,

After a little research I found that when I try to code-fold manually by right-clicking and going to the code-folding option, all 4 options are grayed out and cannot be clicked on. Also, enabling/disabling code folding I noticed that when it is enabled my code is shifted over ~5pixels to, ostensibly, make room for the +/- graphics to be clicked on. However, as I mentioned before, there are no such signs.

Also,I should probably mention that I am running this on a Windows XP 64bit architecture.

doubly thanks,
-alex

Hi,
I’d love to do code folding! BUT, even after using cells in the code and enabling code folding in the preferences menu, there are no +/- signs to click on anywhere in my code to enable code folding.
I’m writing a script .m file(not a function) and running:
MATLAB Version 7.5.0.342 (R2007b)

Also, I have cell highlighting on and it highlights correctly so I know that my cells are correct and the editor recognizes when my cursor is in one.

Is this a version issue?

thanks!

Hi Suresh,

Thanks for the feedback. Note that you can start typing a command in the Command Window and up arrow, which will then cycle through only the commands starting with what you’ve typed. I use this technique all the time to find previously typed commands.

Hi,

I am sorry if this is off topic.

But I find something very annoying in Matlab. The way matlab command history window displays, always “expanded”. Is there any way to set that it is always “collapsed”. It’s very tedious to scroll through it to a specific command in specific date. If it were always “collapsed” then I could go to specific date and expand it to see the list of command on that date.

Hi Steven,

Do you typically want your folds to be shared with other users? It seems that I’d want to remove folds before submitting or sharing code.

I’ve always used folding in vim with the markers
%%FOLDUP
and
%%UNFOLD

I think code sharing would be much easier if there were a single standard, such as this one, which could be used in one’s editor of choice (including the matlab editor) and which persisted with the ascii file…
