Subject: fixed ctrl-drag for expressions, maps, fform doc selections. fixed
 using shift to add Doc to a selection and also when bounding box already
 covers the doc to add.  fixed dragging maximize button to start goldenlayout
 drag properly.  fixed typing character to group,etc a multiselection when a
 text doc has input focus.  fixed using clusters. add Shift-U to ungroup
 alternate group style.  multi-select blurs() all active inputs.
 shift-selecting a multi-selected Doc, deselects it.
