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>
