Chapter 7 - Finding/Buffer
Even though this is a very short chapter, I thought it valuable as it helps to introduce the next chapter on multi-cursors a little bit better.
Find word and add to buffer 
⌘ + G
Let’s open WOTW.md by pressing 
⌘ + O and look for the word “Martians” in the first sentence.
Select this word by pressing shift + ↑, then press ⌘ + G once.
Now the word “Martians” has been added to our Find Buffer. We can easily find the next occurrence of this word by pressing ⌘ + G.
Find next/previous occurrence from buffer kbd>⌘</kbd> + G / kbd>⌘</kbd> + shift + G
See what happens when you keep on pressing ⌘ + G. If all goes well, your cursor should start iterating through all occurrences of the
selected word. Conversely, using kbd>⌘</kbd> + shift + G allows you to backtrack through the usages
(aka. “find previous”)
Now open War.java, position your cursor on 13:33 (line number 13, character number 13) using ⌘ + G. Next, select
the . and press ⌘ + G.
