CTRL key and arrow keys allow in input

<input type="text" id="s" />
jQuery('#s').bind('keyup blur',function()
{ 
    var selectedInput = jQuery(this);
    selectedInput.val( selectedInput.val().replace( /[^a-zA-Z0-9,]/g, '' ) );
});

I want to edit my text from anywhere in the text so I want the arrow keys (left,right,up,down) and plus crtl key to select all the text with ctrl+A.
