I've switched to Mac around 1 year ago and I was disappointed to see that additional mouse keys were not supported out of the box. I've been using SensibleSideButtons ever since.
This is from the same company that thinks that a one-button mouse is a really good idea.
At the time it was quite sensible. Many in the target audience were computer illiterate or beginners. The context menu is not discoverable and is counter intuitive to the point and touch metaphor. In addition, most of the right mouse button actions can be replaced by a two click alternative. Finally, the modifier keys can be used for power users.
This seems to conflict with the long-standing reputation that Macs were for designers.
Graphical designers vs UI designers...
Which makes the current infatuation with gestures even stranger. They're even less discoverable than a second mouse button.
It is. It forces app developers to actually think through their UX/UI.
