TL;DR

| g- | move back 1 chronological changes |

Vim keeps track of an "undo stack", a linear history of all the changes you've made. Adding something in insert mode adds 1 item to the undo stack. Using u or ctrl-r traverses up and down the stack until you being inserting something else.
In command mode, press u to undo the most recent change. Easy!
To redo the most recently undone command, press ctrl-r.
Advanced users will find undo branches useful. Vim actually keeps track of every change you've ever made. Vim uses a tree structure that can be navigated using g- and g+ or :earlier and later. Further reading in this guide on vim undo branches.
