The word labels in goto_word will not change unless the screen scrolled

[HairlessVillager]

In the current version, the word labels in goto_word are based on the cursor's position. It works, but when someone move his cursor to another word, the labels is totaly different.

Let's say there is a text:

Move the cursor to "INTRODUCTION" and then goto_word:

Move the cursor to "Welcome" and then goto_word:

What about this behavior: the word labels in goto_word will not change unless the screen scrolled. If the cursor moves but the screen do not scroll, the labels will be consistent.

Further more, I've studied Rust and can implement this idea. May I create a PR without any suggestions?🧐
