Support additional keys

[DannyBen]

As discussed in #64 - we need the ability to send more keys. Here is a list borrowed from the AutoHotkey list

• F1 - F12
• Enter
• Escape + Esc
• Space
• Tab
• Backspace
• Delete + Del
• Insert + Ins
• Up / Down / Left / Right
• End
• PgUp / PgDn
• CapsLock
• ScrollLock
• NumLock
• Control + Ctrl **
• LControl + LCtrl **
• RControl + RCtrl **
• Alt **
• LAlt **
• RAlt **
• Shift **
• LShift **
• RShift **
• LWin **
• RWin **
• AppsKey **
• Numpad0 - Numpad9
• NumpadDot
• NumpadEnter
• NumpadMult
• NumpadDiv
• NumpadAdd
• NumpadSub
• NumpadDel
• NumpadIns
• NumpadClear
• NumpadUp
• NumpadDown
• NumpadLeft
• NumpadRight
• NumpadHome
• NumpadEnd
• NumpadPgUp
• NumpadPgDn
• PrintScreen
• Pause

** These keys may not be needed in vhs context

Escape seems to be supported already, at least the examples already use it.

As an alternative, maybe it would be a good idea to support sending raw CSI sequences?

There should be support for a lot of the keys on this list. I'd need to double check the source code to confirm, but you can see the supported keys here:

Out of the ones that aren't implemented yet, are there any in particular that users would like to see introduced? If so, please let us know! I'm going to convert this to a discussion in the meantime to track this conversation while keeping our backlog clear :)
