Unit of Work
------------
Changing to insert mode, making edits, and switching back to command mode is
considered one unit of work in vim. The "dot operator" (.) replays the previous
unit of work. This can make it to quickly repeat similar edits, like when you
make an edit and then realize you have to apply the edit a few more times.
