What is a shortcut key that has the same effect as double clicking the left mouse button to select the whole word

Hello experts.

What is a shortcut key that has the same effect as double clicking the left mouse button to select the whole word?

Not ctrl+shift+left/right, ctrl+shift+left/right cannot achieve the effect of double clicking the left mouse button. ctrl+shift+left/right can only partially select words, and often selects extra characters.

thanks.

There is no such shortcut for this, sorry.

Thank you for your reply. Thank you very much.
