I am stuck on a puzzle on level 7 where the player needs to remove the x's from the sentence.
fx will find forward,
t will go txill,
; wixll repeat them,
, rexverse the dexal "
I only have 12 key presses to pass, but I never can complete it. I get to the last step when I have 0 chances left. I believe in this exercise I should use 't\T\f\F' and ';' and ',' buttons, however I am still stuck.
