It is often very comfortable to see where your cursor in VIM is. To achieve that you can use cursorcolumn and cursorline to highlight the row and the column in which you are currently present with your cursor. Below is a function that can be placed in your .vimrc to toggle such a behaviour. It is then mapped to <leader>cl, which effectively means that you need to punch \cl to make it work.
set cursorline
set cursorcolumn
fu! ToggleCurline ()
if &cursorline && &cursorcolumn
set nocursorline
set nocursorcolumn
else
set cursorline
set cursorcolumn
endif
endfunction
map <silent><leader>cl :call ToggleCurline()<CR>
