Editor movement suddenly became very slow

I was editing a landscape and suddenly the arrow keys are moving the scene around about 1/20th of the speed that is usually does. This is making painting textures quite slow to achieve now.

I saved and re-loaded Unity but the problem remains.

Does anyone know what I accidentally set to cause this micro-movement setting? It also does it when you select the hand tool and hold the left mouse button down to move.

I fixed this. After much messing about pressing F and zooming in on the first person camera fixed the issue!

Yup. I had a similar issue where my pan widget was moving incredibly slow. I pressed the ‘F’ key and it’s back to normal.

Pressing F should be the FIRST thing they teach in the tutorial series.
