Allow keyboard controls

…maybe usings arrows → ↓ ↑ ←, space ?

I assume arrows would move the viewbox around, right?
What does space do? ))

I can imagine playing this Factorio-style with right hand on the mouse and left hand on the keyboard. Then the controls could be something like this:

Move the viewbox - WASD (arrows too maybe)
Zoom in / out - R/F (?)
Rotate hovered tile clockwise / counter-clockwise - Q/E (?)
Lock or unlock hovered tile - Space

I doubt I'd actually use keys to rotate tiles but navigating around may be handy).

Here's my idea for a keyboard layout:
include keys for each of C, 180, and CC rotation (I suggest something like the keys l;', to be used with right hand)
a hexagonal layout of keys for each cell around the current cell (perhaps WEADZX)
a pin key (SPACE, or maybe S because it is in the middle of the cell movement keys)

Have the viewbox auto-center on the currently selected cell.

Pick whatever you want for zoom in/out
