I am stuck on level 7 :Removing x's from the sentence

Searches made using f and t are remembered across different blocks of text in the game (and across buffers in vim), so you can use ; and , on the first line using the saved search from your previous attempt to save one keystroke.

In order to finish this puzzle, you need to collect the f, ; and , keys. Note that when you bump into bushes, you sometimes find things - either keyboard shortcuts or people.

You should go back to the Alice text at the beginning of the level (the long one) and go through all the bushes. There are a lot of things to find. It will also make traversing the text a lot easier.

One more thing, if you're still missing one keystroke to finish this text after you collect everything, remember that ; and , repeat the last search within the line, even if it was not performed on the current text.

As said above; using ft,; but.... you cannot complete the puzzle on the first attempt.

Since a list of the precise keystrokes is requested, I've just confirmed this works. Spoilers below.

This puzzle can be done with two passes. First pass:

j to enter the puzzle; 0 to get to the beginning of the first line; fx to search for x, which stores it in the search memory. Now press [esc] twice to quit the first pass.

Second pass:

1. j to enter the puzzle;
2. , to search backwards for the x, then x to delete it;
3. j down to second line;
4. ; to repeat the search forwards for x, then x to delete it;
5. j down to third line;
6. , to repeat the search backwards for x, then x to delete it;
7. j down to fourth line, already on the x so x to delete it;
8. finally, ; to repeat the search forwards for x, and x to delete it.

Happy Vim Adventuring!
