Zorlac, you can enter numbers, but you have to know the commands that correspond to them - or maybe even you have to set them up on your keyboard.
Mine looks like this (but I may have added them):
KEY_ALT_0=UFC_F00
KEY_ALT_1=UFC_F01
KEY_ALT_2=UFC_F02
KEY_ALT_3=UFC_F03
KEY_ALT_4=UFC_F04
KEY_ALT_5=UFC_F05
KEY_ALT_6=UFC_F06
KEY_ALT_7=UFC_F07
KEY_ALT_8=UFC_F08
But I think actually these are UFC function keys, which are not the same as the UFC keypad keys. But those are also in there, just have to find them and set them up to correspond with a keystroke.
In game, go open into settings, under controllers, then keyboard and have a look there. You can add these commands to keystrokes there.
For reference later, what I do is open the f18keys.ini file and print it. Then I can make notes, etc. I found that useful when programming the X52.
For a better understanding on this, see the TSHv3 site in Joe's sig. Here is the table of contents.
