The last special strings to mention are wordstart and wordend. If you have an index which is in the middle of a word, you can use these two strings to refer to the beginning and end of it.

For example, if you knew that the y of Python was at 3.2, then 3.2 wordstart and 3.2 wordend would refer to the beginning and end of this word.

Let's build upon our demo application by creating some keyboard shortcuts which will utilize a few of these tools.
