Replace with next value (ctrl shift dot) in Visual Studio Code

Question

Does anyone know how \"Replace with next value\" (ctr + shift + dot) works ?

I am unable to get this shortcut to do anything on my vscode.

I tried googling

Answer 1

If I press the shortcut after highlighting an integer or float literal (16 or 5.2 for example) it subtracts 1 from it.

Strangely, Replace with Previous Value adds 1 to the value while Replace with Next Value subtracts 1.

I don't know if it has any other purpose.
