ir remote howto figure out which keys are being pressed?

[abs0lut.zer0]

hey all 

i bought a ir remote which works fine except for the fact i cannot get up the delete [context menu] menu

how do i figure out which keys are being pressed with this remote in order to modify the keymap file for kodi to my liking...

is there a program that can tell what is the keycode this remote uses if i press a key?

thanks for any help..
