Registers

Special registers
@ followed by a register symbol represents a register. In addition to the standard numbered registers @[0-9], there are several special registers.
:: command register
/: search register
%: filepath register
": last yanked value register
+: system clipboard register
=: expression register
:reg for a complete list.
Modify register contents with <Ctrl-r>REGISTER
Note that since macros are just command sequences stored as a string in a register, you can edit macros this way as well.
:let @q='<Ctrl-r>q' # ...and then modify
Reuse contents of search register
Useful for when you search for something unwieldy to type and need to reuse it later (for a replace for example).
/some-long-and-complicated-search-string # search something arcane
:%s/<Ctrl-r>//replacement-string # reuse without retyping
Yank to system clipboard
"+y
Set system clipboard contents to current filepath
:let @+ = expand("%")
Run function on search results
Useful for transformations. The following will dashcase all capture group matches using abolish.vim.
g/\attribute :(\w\+\)/\=g:Abolish.dashcase(submatch(0))
