I noticed a few more things in how I type. I use it as a modifier for all symbol-keys on the right hand side.
However, I recently noticed that I press down the right Shift key at different places for different keys using different fingers.
For the keys just to the left of Shift, I move my right hand down to the shift key, put my index finger over the symbol - and press both the middle and ring fingers on the left side of the Shift key.
For the symbol keys above it, I press both the ring finger and pinky on the right side of the Shift key.
