As I saw in this forum there are a lot of people that want to add chords to the text files.
As you now if you use Space or TAB in between the chords may be your keyboard (mine is pa800) is not able to load it correctly.
e.g.:
Am B E D
May be shows as:
AMBED

Solution you have to use an asci code for making spaces the code is like this:
Desktop computer:
1-Press the Num lock button on the keyboard
2-Hold down the ALT key
3-In the Num pad type 255 (when you are holding down Alt key)
4-Release ALT key
Result: you will get a SPACE
Laptop users:
1-Press the Num lock button on the key board
2-Hold down the ALT key and Fn (function) key
3-Type 255 by pressing KII keys (when you are holding down Alt+Fn keys)
4-Release Alt and Fn keys
Result: You will get a space

Good luck
