         17 . A cellular telecommunication device without a keypad, operative to receiving incoming calls, comprising:
 a cellular radio for receiving incoming voice calls;   a speaker coupled with said cellular radio for outputting voice from said cellular radio;   a microphone coupled with said cellular radio for inputting voice to said cellular radio;   a digital tape recorder;   an incoming call filter;   control keys A and B; and   circuitry for said control keys, coupled with said cellular radio, said digital tape recorder, said incoming call filter and said control keys, operative to:
 in response to key A being pressed, re-dial the number of a last incoming call, and 
 in response to key B being double-clicked, set the device in a special operational mode whereby:
 in response to key B being pressed, start or stop said digital tape recorder, and 
 in response to key B being subsequently pressed, activate or de-activate said incoming call filter. 
 
   
     
     
         18 . The cellular telecommunication device of  claim 17 , further comprising a dialer for dialing an outgoing call, wherein said circuitry is further operative in the special operational mode, in response to key B being subsequently pressed, to dial a next call in a pre-specified queue of outgoing calls. 
     
     
         19 . The cellular telecommunication device of  claim 17 , further comprising a dialer for dialing an outgoing call, wherein said circuitry is further operative in the special operational mode, in response to key B being subsequently pressed, to activate or deactivate voice dialing via said microphone. 
     
     
         20 . The cellular telecommunication device of  claim 17 , wherein said circuitry is further operative, when an incoming call is first received by said cellular radio, to accept the incoming call in response to key A being pressed, and to reject the incoming call in response to key B being pressed. 
     
     
         21 . The cellular telecommunication device of  claim 17 , wherein said circuitry is further operative, when an incoming call is in progress, to terminate the incoming call in response to key A being pressed, and to start or stop recording the incoming call by said digital tape recorder in response to key B being pressed. 
     
     
         22 . The cellular telecommunication device of  claim 17  wherein said circuitry is operative to provide audio feedback via said speaker when it sets the device in the special operational mode. 
     
     
         23 . The cellular telecommunication device of  claim 17  further comprising a light emitting diode coupled with said circuitry, and wherein said circuitry is operative to provide a visual indicator via said light emitting diode when it sets the device in the special operational mode. 
     
     
         24 . The cellular telecommunication device of  claim 17  having the form factor of a pen. 
     
     
         25 . The cellular telecommunication device of  claim 17  having the form factor of a pen cap. 
     
     
         26 . The cellular telecommunication device of  claim 17  having the form factor of a necklace. 
     
     
         27 . The cellular telecommunication device of  claim 17  having the form factor of a wristwatch. 
     
     
         28 . A method for operating a cellular telecommunication device without a keypad, having circuitry for two control keys, A and B, comprising:
 in response to key A being pressed, re-dialing the number of a last incoming call;   in response to key B being double-clicked, setting the device in a special operational mode, comprising:   in response to key B being pressed, starting or stopping a digital tape recorder; and   in response to key B being subsequently pressed, activating or de-activating an incoming call filter.   
     
     
         29 . The method of  claim 28  wherein said setting the device in the special operational mode further comprises, in response to key B being subsequently pressed, dialing a next call in a pre-specified queue of outgoing calls. 
     
     
         30 . The method of  claim 28  wherein said setting the device in the special operational mode further comprises, in response to key B being subsequently pressed, activating or de-activating voice dialing. 
     
     
         31 . The method of  claim 28  further comprising, when an incoming call is first received:
 in response to key A being pressed, accepting the incoming call; and 
 in response to key B being pressed, rejecting the incoming call. 
 
     
     
         32 . The method of  claim 28  further comprising, while an incoming call is in progress:
 in response to key A being pressed, terminating the incoming call; and 
 in response key B being pressed, starting or stopping recording of the incoming call by the tape recorder. 
 
     
     
         33 . The method of  claim 28  wherein said setting the device in a special operational mode comprises providing audio feedback via a speaker. 
     
     
         34 . The method of  claim 28  wherein said setting the device in a special operational mode comprises providing a visual indicator via a light emitting diode.
