Disable function tips, suggestions, help pop-up in Editor R2021b macOS

28 views (last 30 days)
I would like to turn off the function suggestions that pop up while typing in the editor. This used to be accomplished in Preferences>Keyboard> and deselecting Function Hints, but that is no longer there. Did not seem like a logical place for that preference, I will admit, but I cannot find it anywhere now.

Hi @Dirk,
In MATLAB R2021b, the option to disable function syntax hints in the MATLAB editor is no longer supported.
However, you can disable function syntax hints in the MATLAB Command Window. You can also choose Code Suggestions and Completions to only appear after the you press the tab key (which are similar to, but not the same thing as function syntax hints).
Refer this link to know more on how to disable Automatic Suggestions and Completions.

Hi Srijith,
The issue is with function syntax hints in the editor, not the other scenarios you describe in your answer.
Why is the option to disable this is no longer supported? Why can one disable it in the command window, but not the editor? Will this option be restored in a future release?
I find these pop-ups while typing to be very disruptive to composing and editing my code, often blocking visability and movement using the keyboard controls (e.g. up/down arrows), requiring use of the mouse, etc. to navigate out of the "sticky" hints widget.
I am also a little puzzled by these repeated "answers" (first via email two months ago, now here) suggesting to do something entirely different. If I bring my car in to the dealer and tell him my front windshield wipers are stuck on all the time, would you expect him to tell me how to turn off my rear wipers or my fog lights? Your first sentence was a clear and accurate answer. Thanks.

@Dirk, would you mind trying this:
  1. Go to Preferences
  2. In the menu on the left, click into MATLAB > Editor/Debugger > Automatic Completions
  3. Under Suggestions and completions, check Show on tab
  4. Click OK
This will stop the function suggestions from popping out automatically while typing, unless you explicitly hit <tab> key.

It is indeed very disruptive. I have tried many ways to disable these suggestions.
