Stuck on level 7 "if (practice) {" section
Solution 1:
First of all, you'll need %.
That said, here's a hint: you won't need to use % on the parentheses, only the curly braces.
If that's not helping, comment with your best sequence so far and we'll go from there. :)
Solution 2:
Assuming you collected the g from the house near the beginning of the level, you can get to the start of the content to be deleted with two moves remaining and then use dG to delete until the end of the text.
As clozach mentioned above, you can alternatively get the % from the nearby hut and use d% to delete until the end of the else block.
