Actually, I find both of them too complicated to use, I want a quick and
easy blind-typable variant.  I got two ideas:

1. How about "< -" or "< --" for \longleftarrow?
   Pro: the spacebar is the most easy key to hit
   Con: not totally transparent/self explainable

2. Use P. Boekholts autotext and define
   new_autotext_item("<--", "\longleftarrow);
   new_autotext_item("<==", "\Longleftarrow);

   Pro: completely consitent
        actually, using autotext one can replace latex_arrow ()
	  with the according autotext definitions
	  -> more easyly customizable by the user
   Con: dependence on an external mode
