I'm just very used to the fast repeat rate on my Ubuntu workstation and recently started using my MacBook. I like having high repeat rate because it allows me to navigate much faster in my editor while developing stuff.

It's just bizarre that Mac OS has such a small cap on the Key Repeat rate. Wondering if there is a way around this.
Edit: I do have a powerful plugin [0] for jumping which I often use, but still - in some cases I just want to scroll all the way there. Fast.
