Is it possible to control everything with keyboard

Hi,
I purchased a MS joystick, now I would like to eliminate the mouse and use only the joystick and the keyboard.
I re-defined all the controls I need (radios, A/P switches, OBS, hd selector, etc.). But I have diffuculty at altitude hold switch. I mapped it to letter "I", but when I press, it just toggles fight director on, and activates wing leveler.
Moreover, I could not find the IAS adjust selector.
I read somewhere in this forum that someone done such a thing for CFS, i wonder if it is possible with FS2002.
Thanks.
