It's been a few months since I got my new iMac and with it was forced to switch to Mountain Lion. I've more or less made my peace with everything except this -- the arrows on the scroll bars are gone. This means what was once an automatic operation that required almost no thought now requires me to swtich gears, locate the thumb and move it different amounts depending on how long the document is. When I first observed this, people said not to worry -- you'll get used to the new way of doing things. But the New Way so far has not revealed itself. So please, do tell, what's the recommended fast way to get the current window to scroll just a little in one direction or another, using the mouse? I have a Magic Mouse, of course. I've tried all combinations of gestures, and nothing seems to do it. Is there a howto somewhere?
The variety of answers in the comments show how much Apple f'd up with this.
I miss the arrows, hate the new extra-narrow width of the scrollbar (which requires the hands of a safecracker to hit accurately), and hate both the magic mouse and the magic trackpad. I don't want magic. I want function. Straightforward, uncomplicated does-what-you-expect function. Obvious visual affordances. Clear physical boundaries between right and left. Stuff like that.
Color me cranky, but I do feel screwed by all these changes.
BTW & FWIW, I gave away my magic trackpad and kept the magic mouse. I'm using it now with the fancy shit disabled. I use the arrow keys and page-up and page-down, home and end keys, on a wide aluminum USB keyboard Apple no longer makes. The new little bluetooth keyboards Apple now sells don't have the page up and down, home and end keys. More value subtraction.
Oh, and I miss the 17" laptop as well. It was great while it lasted.
My next phone will be an Android and my next laptop will be pure Linux. I'll keep this 3-year-old 15" Macbook Pro for photography, since there is much that Photoshop and Lightroom do that the Gimp still doesnt. But I'm near the end of my patience with giant companies trying to control everything. That's the current plan. Just saying.
