title: how to remap key : to go in vim command-line mode?
body: <p>Using a Italian keyboard, to switch to command-line mode from any other mode(normal, insert, visual) I need to (<kbd>ESC</kbd>) ad press key </p>
  
  <p><kbd>:</kbd></p>
  
  <p>Because the keyboard aforementioned, the COLON key require pressing TWO keys: </p>
  
  <p><kbd>SHIFT</kbd> <kbd>:</kbd> </p>
  
  <p>There is a way to remap the <kbd>SHIFT</kbd><kbd>:</kbd> with maybe <code>&lt;LEADER&gt;</code> (or a function key <kbd>F1</kbd>) ?
  I presume I need some <code>?map</code> setting in <code>.vimrc</code> but I didn't have success in my tempts.</p>
  
  <p>BTW, <kbd>SHIFT</kbd><kbd>:</kbd> is one of things a bit slow-down editing in <code>vi</code>, for me.</p>
  
  <p>thanks</p>
