CTRL-B or <Home>
        cursor to beginning of command-line
CTRL-E or <End> 
        cursor to end of command-line
CTRL-H              
<BS>        Delete the character in front of the cursor (see |:fixdel| if
        your <BS> key does not do what you want).
<Del>       Delete the character under the cursor (at end of line:
        character before the cursor).
CTRL-W      Delete the |word| before the cursor.  This depends on the
