How to turn on the function hint?

Hi!

As I know by default the function syntax hint is already on, but when I am typing in command window nothing showing up. I check in Preferences option making sure that the function hint is enabled.

I tried to re-install the MATLAB still doesn't work.

Please help.

Syntax hinting and function completion are available in both the Command Window and Editor, and are on by default:

http://www.mathworks.com/help/matlab/matlab_env/check-syntax-as-you-type.html

http://blogs.mathworks.com/community/2008/10/20/function-hints/

The documentation states:

"To use function syntax hints, type a function name with an opening parenthesis, and then pause. A tooltip opens showing the basic syntax for the function"

"To complete names in the Command Window, type the first few characters of the name you want to complete, and then press the Tab key."

The documentation also tell us how to turn it on and off: "Function hints are enabled by default. To change this setting, on the Home tab, in the Environment section, click Preferences. Select MATLAB > Keyboard, and then set the options for Function hints."

Hello:

I have the same problem with the 2019 version. I've tried everything I've found in Mathworks and over the internet, I've installed the last version 2019a (5), and the last Java Version available and it's still not working the auto code suggestions nor the copletions unless I press on Tab key ( as I can see in the online version the suggestions appears while you type without pressing the tab key)

I can see how that feature should work in the web version, which I'm using for a tutorial, and I can say that would be great and very helpful if I could use it in the desktop version.

I'd appreciate very much if you could help me with this issue.

Thenx!

you can also press ctrl+F1 while inside the parenthesis to make it pop out.
