The subject pretty much says it all. The decimal form is what’s required to enter a character in Windows via the A+numpad method.
- Shortcut Ctrl+J = Decimal code-points
- Shortcut Ctrl+K = Hexadecimal code-points
Is that what you want? Unless the grid square are very large there is not enough space to show them both. One can choose between: Automatic, Glyph Name, Index, Code-point, or Unicode Name for the glyph overview captions.
