Hi Aleksey,
It is my understanding that "Ctrl + +" shortcut is working fine for folding code in MATLAB Editor and not in App Desginer. It might be because the shortcut is already mapped to a different function, which is why it zooms in instead of folding the code.
Please try if "Ctrl + ," shortcut works for folding code in App Designer. If "Ctrl + ," shortcut doesn't work in App Desginer, please follow the below steps to enable the shortcut :
- Click on the "Home" tab.
- Click on the "Preferences" button in the "Environment" section.
- In the preferences window, click on the "Keyboard" tab.
- In the "Keyboard Shortcuts" section, search for the "Fold All" command.
- If the command is not listed or does not have a keyboard shortcut assigned, you can add the shortcut by selecting the command and clicking on the "Add Shortcut" button. Then, press the "Ctrl + ," keys to assign the shortcut.
- Click "Apply" and "OK" to save the changes.
Once you have enabled the keyboard shortcut, you should be able to use "Ctrl + ," to collapse all code sections in App Designer code view.
I hope this helps resolves your query.
