Allow the user to tab through distance parameter fields in the multiple ring buffer tool.
Pressing Tab from the selected box currently skips ahead to the 'Add another' button (Pro 3.1).
Using <Space> to add another, I would expect to either have the new line highlighted or at least to be able to Shift+Tab back to it, but it just returns me to the '15' line. This slows down my workflow, having to reach for the mouse, move it, and click to input each distance, rather than simply tapping tab.
