Who's done this...

When typing 'www' for webpages, you use the fingering 3-2-1....

i dont even do that on the piano

[Waldszenen]

Nah - computer keyboard keys are too small for me to repeat them.

[BoliverAllmon]

nah. I never leave the proper hand position. just use the same finger.

Yeah, it is much easier to use one finger on the keyboard to type www.... but still its fun to do.  But on piano, I have to use different fingers in order to play extremely fast repeated notes.  Slow repeated notes are fine with one finger, but try doing that in something like Alborada del Gracioso and you're screwed!
