exercise 5 of 10

change and search

c is change: delete what the motion covers, then enter insert mode. cw changes to the end of the word.
* searches for the word under the cursor; n goes to the next match, N to the previous.

Rename tmp to total. Search, change one, then n. for the rest. The search wraps around the end of the file.
