I have a form with a mix of text, number and checkbox input. As you probably allready know itīs possible to tab through the unlocked input cells one by one. But I canīt include the checkboxes in this tabbing. Now the user have to use the mouse to select or unselect the boxes. I find this annoying and wish that it was possible to check/uncheck with tab and space.

How do I do to make the tab sequence include the boxes?
