Title: On-screen diagonal cursor navigation on a handheld communication device

Abstract: Method and arrangement for affecting diagonal movement of a cursor 171 on a display screen 322 of a handheld communication device 300. The method includes sensing movement at an auxiliary user input 328 of the handheld communication device 300 indicative of a user's desire to affect diagonal movement of the cursor 171 on the display screen 322 of the handheld communication device 300. X-direction signals and Y-direction signals are produced based on the sensed movement at the auxiliary user input 328. During that time while necessary signals are being collected and processed, the cursor 171 is held steady on the display screen 322 until a predetermined criterion is met for discriminating whether the user has indicated x-direction cursor movement, y-direction cursor movement or diagonal cursor movement.
