Claim:
A method for using a medical instrument, comprising: receiving a user input selecting a function from a menu; tracking a frequency with which each function is selected from the menu, wherein the frequency is used for defining hot keys; associating the hot keys with functions according to the frequency with which each function is selected from the menu, by: determining a frequency value for each function in the menu by evaluating the expression X=F*N, where X is the frequency value for a function, F is the frequency that the function is selected, and N is a preset coefficient, wherein N is determined based on an importance of the respective function and a difficulty in selecting the respective function from the menu, wherein the importance of the respective function is independent of the frequency that the function is selected or other user input; and selecting the functions with the highest frequency values in the menu to associate with the hot keys; and displaying the hot keys in the hot key display area on a display device of the medical instrument.
