WebUI - axis movement by cursor keys

[luc-github]

From Grbl_Esp32 created by JensHauser: bdring/Grbl_Esp32#791

Please describe the feature you would like implemented Up/Down and Left/Right cursor keys for x/y axis would be very helpful as a solution for making movements.

What do you need the feature for? I use a laptop with WebUI to move the x/y axis to the right location. Hitting the circle field and in parallel watching the cnc mill is not that easy :-) Taking cursor keys, e.g. in 10mm steps, would be better.

Will this feature appear to a lot of users? I hope so.

In 3.0 the plan is to use button UI instead of pronterface for Jog: https://github.com/luc-github/ESP3D-WEBUI/issues/144#issuecomment-764845963

Access Key has been discussed here: https://github.com/luc-github/ESP3D-WEBUI/issues/108, but I did not digged in to solve the problem yet

about access-key, this https://developer.mozilla.org/en-US/docs/Web/HTML/Global_attributes/accesskey explain that they behave differently according OS and browser and may need several keys at once - which is not really great, so solution does not fit dirrections keys In addition it seems recommendation is actually :

it is generally advised not to use accesskeys for most general-purpose websites and web apps.

So I think I will use onkeydown for up/down/left/right arrows on main container https://www.w3schools.com/jsref/event_onkeydown.asp when jog panel is visible

POC is now implemented in printer using keyboard eventListener - I meet a problem with removeEventListener that seems not working with preact for some reason, so I have add some hack until fix is found The Printer UI use Pronterface but for keyboard it switch to mobile UI, for not printer UI that do not use pronterface UI (e.g CNC) the UI will stay the same (button style UI)

Thank you, Luc. I guess this enhancement will be part of next ESP32/Fluid distro, so I´m curious to make use of it

@JensHauser for what I can see fluidNC use Mitch fork with cncjs UI which has already this feature if I am not wrong
