+#### Change cursor style in insert mode
+
+I like to use a block cursor in normal mode and i-beam cursor in insert mode.
+Also when using tmux in the middle.
+```viml
+if empty($TMUX)
+  let &t_SI = "\<Esc>]50;CursorShape=1\x7"
+  let &t_EI = "\<Esc>]50;CursorShape=0\x7"
+else
+  let &t_SI = "\<Esc>Ptmux;\<Esc>\<Esc>]50;CursorShape=1\x7\<Esc>\\"
+  let &t_EI = "\<Esc>Ptmux;\<Esc>\<Esc>]50;CursorShape=0\x7\<Esc>\\"
+endif
+```
+This simply tells Vim to print a certain sequence of characters ([escape
+sequence](https://en.wikipedia.org/wiki/Escape_sequence)) when entering/leaving
+insert mode. The underlying terminal will process and evaluate it.
+
+There's one drawback though: there are many terminal emulator implementations
+and not all use the same sequences for doing the same things. The sequences used
+above might not work with your implementation. Your implementation might not
+even support different cursor styles. Check the documentation.
+
+The example above works with iTerm2.

 #### Don't lose selection when shifting sidewards
 
 If you select one or more lines, you can use `<` and `>` for shifting them
