Keystroke Commands

$3

Toggle between document / multiline object creation mode or line mode

When in document / multiline mode, lines are inserted into an object with UNIX time as their keys. This may be used to sort the document when it is returned.

Exit this mode, save and emit the document / multiline object (if it has data) with CTRL+W or OPT+BACKSPACE.

$3

Paste data from the clipboard into the document

> Note: COMMAND-V does not work to paste from the clipboard. This is a limitation of the OS terminal.

$3

Exit the application

$3

See readline TTY keybindings documentation

$3

Creates a new instance of Carets

#### Example
`js
let params = {
caret: 'carets > ',
docCaret: '$ '

let carets = new Carets(params)
`

Document mode treats the first line entered as the document name. Each subsequent line is the document body. You may paste multiline data from the clipboard with CTRL-V.

#### params

##### params.caret
The string you would like to use as your caret

##### params.docCaret
The string you would like to use as your caret in document / multiline mode
