[Feature]: moving keymapping elements using arrow keys

[FlyMeToTheMoonAndLetMePlayAmongTheStars]

Is your feature request related to a problem?

yes, minor issue

its hard for the user to place WASD keymap input over in-game joystick with good precision, often you're off by a few pixels and the joystick ends up looking janky when you press on it

Describe the solution you'd like

• change the keyboard shortcut for upsize/downsize selected keymap element from cmd + up arrow and cmd + down arrow -> cmd + + and cmd + -
• implement move selected element controls, movable in small increments (1px?) by cmd + directional arrow keys

Anything else?

nothing for now

One issue about the + and - is that some keyboards have different placements so it might be a little weird... maybe cmd + shift?
