~ original vi had only one level of undo
~ yikes!
~ vim has unlimited (limited only by memory)
~ set ‘undolevels’ to what you need (1000
default)
~ simple case: u – undo, CTRL-R – redo
~ vim 7 introduces branched undo
~ if you undo something, and make a change, a
new branch is created
~ g-, g+ – go to older/newer text state (through
branches)
~ you can travel through time
~ :earlier Ns,m,h – go to text state as it was N
seconds, minutes, hours ago
~ :later Ns,m,h – go to a later text state similarly
~ :earlier 10m – go back 10 minutes, before I
drank a can of Red Bull and made all these crazy
changes. Whew

stty intr
stty erase
stty echoe
