Widget blueprint no curve editor and play animation button?

Hi everybody, in widget blueprint I can create a text fade effect animation but I don’t have curve editor and also play button for animation in timeline window. Is hidden or what? I only have autokey and snap buttons

There are play buttons for animated widgets. If you’re missing a window make sure you have Timeline selected. Check out: Animating UMG Widgets in Unreal Engine | Unreal Engine 5.2 Documentation

Tested in 4.8.3

Thank you for your answer but look at my screenshot !

What version do you have? Mine is 4.7.3

The screenshot was from a 4.8.3. build.
from 4.8 release notes “New: Add animation playback support to the widget editor.”
