Wow, interesting translation for installer!
Some fresh ideas, not just "test2" or "test4", maybe need to do something like that for english and russian too!
About stat_txt:
What you changed - are highligthed letters only, not hotkeys. Hotkey is the 1-st small letter:
c<1>ENTRENAR CAM<4>P<1>ESINO<0>
here's "P"is highlighted, but hotkey is still "c".
to change a hotkey you should change it to
p<1>ENTRENAR CAM<4>P<1>ESINO<0>
