+# Breaking The Undo Sequence
+
+Generally, the sequence of undo-able actions is segmented by command. When
+entering Insert mode, everything typed until exiting Insert mode is part of
+a single undo-able segment. If you are going to be typing in Insert mode for
+a while though, you may want to break it up a bit. Without leaving Insert
+mode, hit `ctrl-g u` to mark a break in the sequence of undos.
+
+For example, starting in Normal mode and then typing
+`iabc<CTRL-G>udef<CTRL-G>ughi<ESC>` will leave the buffer with:
+
+```
+abcdefghi
+```
+
+Hitting `u` once will leave the buffer with:
+
+```
+abcdef
+```
+
+Hitting `u` again:
+
+```
+abc
+```
+
+Hitting `ctrl-r`:
+
+```
+abcdef
+```
+
+See `:h i_CTRL-G_u` for more details.
