Using Manual Measure with PGenerator, if I click into one of the Patch Colour RGB Value text boxes and manually type in a new value, but then hit Tab instead of Enter, the Value box and Slider get updated to the value I entered, but the patch displayed by PGenerator is not correspondingly updated.

Has nothing to do with PGen.
As you have not 'actioned' the change (using the Enter key) the colour change is not sent to the patch at all.
The slider value initially changes, but that is all.

While not a bug, maybe we should stop the Tab operation between the value boxed...
Not sure.

Can you point at any other app where Tab is supported but doesn't 'action' the change? In your own UI, using Tab on the Limit Range field or Max Target Luma field appears to 'action' the change.

The tab function to change RGB values does not accept numeric input. For each field, you must select it with a mouse. It would have been convenient to be able to change RGB values using the tab key. Personally, I don't mind using the enter key to reflect the changes.
