Thanks you very much for your replies! I spend a lot of time in the web in search of answer on this question and i really tried to use this :

This is really works in my xterm (n900 with the last sotware updates). Maybe i did something wrong in the past. Thank you very much again! But taping on the screen is possible only for F1-F6 buttons in my local mc and it also doesnt work when you open mc over ssh (on remote server). Now i can connect to my server, open mc and write php, c, java everywhere im so happy...
