oh i see, tab/shift+tab works as excepted when editing on canvas. i just mentioned the property editor.
i just re-checked the situation.
i put a formpanel and some textfields and in component config, i tabbed and shift/tabbed, it has a strange behavior. it sometimes goes up sometimes goes down. but in a crowded project it never goes up i think "applying changes" phase takes sometime and prevents the focus to be moved correctly.
Ok gotcha. Yeah the shift+tab addition was for inline editing. The property editor is a little quirky, I'll work on that. You can use traditional arrow keys to move around as well. Thanks for reporting.
