##<C-r>{register}
paste Character-wise regions of text from Insert mode. The text from the register is always inserted in front of the cursor position.
<C-r>": insert the contents of the unnamed register.
<C-r>0: insert the contents of the yank register.
Pasting Line-Wise Regions
##p P
put the text before or after the current line.
##gp gP
put the text below or above the current line.
but they leave the cursor positioned at the end of the pasted text instead of at the beginning.
P would leave our cursor positioned above the inserted text.
gP would leave our cursor positioned on the second duplicate.
