Grid tricks: paste to selection. 

NEW: By default a clipboard is pasted to a grid starting from the
cursor position and doesn't matter is a selection of cells present or
not. Often a grid represents the data of a few similar objects like
components, for example. Some number of cells (fields) may have the same
value for a few rows (components). In this case, when filling data we
must copy the range of identical cells from the first row of similar
components and then paste it to every row of the rest components (by
default). From now it may be done easier. We must copy the range of
identical cells from first row of similar components (here is no
changes) and then select rectangular range of cells (for multiple rows)
where must be placed copied data. After pasting copied cells will be
pasted to every selected row.
So in general, we can copy cells from one row and paste it to multiple
rows at a time.
This new feature also makes possible to copy value from one cell and to
paste it to all from the selection.
If copied range of cells is larger than the selection then only the part
of clipboard that matches the selection will be pasted.
