I have a very old mouse which doesn't have a middle mouse button working so I rebound it LCtrl until new mouse arrives. However the mouse binds I had for Larian games had both HOME and O keyboard functions mapped to the side mouse buttons and represents "Center Camera" and Tactical View view toggle. This makes snapping back front and center when edge panning faster.

No other game has rewarded my low impulse control with so many glorious unintended consequences.
