Perhaps I should simplify my request like this: Please give us the ability to change which mouse button is assigned to each of the functions currently assigned to mouse buttons to other mouse buttons. I have also changed the subject title to make this clearer.
It is not to find a specific pre-assigned tile, nor to display the map with that tile centered. It is a function that already works with the LMB (left mouse button),. When you click the LMB on any spot on the main map, the main map is shifted with the display centered on that spot. When you click and hold the LMB on a spot on the main map you can drag that spot to anywhere within the display. I want to re-assign those functions to another key or mouse button (I want to use the middle mouse button, but I think it should be re-assignable by anyone to any mouse button they want).
Along with this, since I want to use the middle mouse button for this function, obviously, I would need to be able to re-assign that button's current function to another mouse button. And so on for all three mouse buttons.
