"The cursor translation lever..."
Google translate isn't perfect
word "перевод / перевести" in russian has many meanings.
1. to translate (translate text)
2. to take across / to lead across (to take somebody across the street)
3. to transfer (to transfer the money)
4. to switch (switch lever to standby mode)
5... and many other.
But in this context correct translating is "movement" (cursor movement lever)
