Add support for keyboard actions #119
Description
Is your feature request related to a problem? Please describe.
There is a method on driver() called keys() that allows one to send a string via the keyboard to an app. This receives a format error from the Appium server. But presenting the same key sequence as performActions keyDown keyUp works.
Describe the solution you'd like
A new method specifically for keyboard input. I will try and add it as a Custom Command.
Describe alternatives you've considered
Adding it directly to the driver is a bit disruptive.
Additional context
Keyboard input by performActions does not have to address a field. Keyboard input does not work for some Apps in Appium Inspector.
