vim key sequence as function argument

I want to execute the command "yiw:s/\<<C-r>"\>/<C-r>"/g<Left><Left>" by key sequence. So I make a mapping

    nnoremap <F7> yiw:s/\<<C-r>"\>/<C-r>"/g<Left><Left>

This mapping copy the word under cursor, then the string :s/\<">/"/g" (where " are substituted by the copied word) appears in the command line and the cursor in the command line is at the end of replacement statement.

I also want to save cursor position before this command and restore after.

  function! SafeCommand(cmd)
let line = line('.')
let col = col('.')
// execute cmd here 
call cursor( line, col )
  endfunction

How to do that?

Normally, you'd just put the entire (complex) command in a function, and invoke that function from the :nnoremap. But that doesn't work for incomplete commands, like the template :substitute that your mapping represents. For that, you need to include the save / restore parts into the command-line (though that's ugly):

:fun! Save()
    let s:line = line('.')
    let s:col = col('.')
:endfun
:fun! Restore()
    call cursor( s:line, s:col )
:endfun
:nnoremap <F7> yiw:call Save()<Bar>s/\<<C-r>"\>/<C-r>"/g<Bar>call Restore()<Left><Left><Left><Left><Left><Left><Left><Left><Left><Left><Left><Left><Left><Left><Left><Left>
