Ok, I do believe you are very good with the keyboard , you are what i call (with no bad meaning ) a pianist.
Having said that, i'd reckon you are using a mac. Mac use to have only one button on the mouse, and people got used to become master with the use of keyboard.
I started with pc and even if in the last 15 years I tried, also very hard, a Mac i never got used to it and i'd always go back to pc. Simply when you start one way is difficult to change habitudes. (don't wanna start a mac pc war)
I always used more the mouse than the keyboard.
But still even if you don't find the need, would you believe other people would?
I believe you pianists don't need it, I wish i was good at the keyboard as you are..
but I am sorry, I am not , and I'm asking your support for my Handycap
