#### 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
