What happened to the fx button next to the Command Window? (2024b to 2025b)

Hello, all.

I recently updated from version 2024b to 2025b. In 2024b, the command window had a little fx button next to the ">>" where you would type code. If you pressed the fx button, it'd pop up a little window and you could search any command, which would give very basic documentation for it.

In 2025b, that button is gone. Is it possible to reactivate it?

The Function Browser (accessed via the "Fx" button) has been removed from MATLAB starting in release R2025a.

Although the function browser is no longer available, there are several alternative methods to access function help and browse available functions in MATLAB R2025a and later:

1. Using the Command Window and F1 Key:

• If you know the name of the function, type its name in the Command Window and press F1. This opens the documentation page for that function in a new window.

2. Browsing the Online Documentation:

• Visit the MATLAB Function Reference List to browse functions by category.
• You can also use the search bar at the top of the documentation to find functions and topics.

3. Using the "help" and "doc" Commands:

• Enter the below command in the Command Window to view summary information.

help functionName

• Enter the below command to open the full documentation page for a specific function.

doc functionName
