<Ctrl-r>

In insert and command mode, <Ctrl-r> followed by a sequence inserts an object.
Insert mode usage mainly deals with manipulating registers. However, in command mode, <Ctrl-r><Ctrl-*> inserts special objects for certain *:
F: Current filename under cursor
P: Current filename with expanded path under cursor
W: Word under cursor
A: WORD under cursor
L: Line under cursor
For more, :help c-^r.
Insert word under cursor
Very useful with :Ag, or when doing find/replace.
:Ag <Ctrl-r><Ctrl-w>
:%s/<Ctrl-r><Ctrl-w>/replacement-string
