FN+SYM key for special Characters-Need Help

[LeonMx]

Hi all.
In my other devices with hardware Keyboard i.e. Xperia, HTC Tilt I, and Eten M700, I used the keys FN+SYM to enter special characters (with the aim of the sym.0409.txt file). For example: I pressed the "a" key then pressed FN+SYM key, then de "a" has been changed to "á" and so on. In the TP2 displays the symbols software keyboard.
Any body knows the reg. key for use the FN+SYM key like described above???


Thanks in advance.
