First, at one point I believe option-click and command-click where built into the old MacOS as proxies for center and right click respectively. That is also the standard for Apple's X11 for MacOS X. XTerm may vary. Don't get me going about X-11.

Why are people talking about control-click?

While I concur with most of your comments and rants please consider this. I use a 17" AlPB laptop. I specifically don't carry around a multi button mouse because there are many places it's either inconvenient or impractical to use a mouse.

No matter whether you like it or not, the Apple standard is currently a one button mouse. Assuming anything else seems dubious. For the record I think a one button mouse is the right choice for the vast majority if lusers.

*flame on. feel free to ignore this rant*
The fact that Cocoa can't do some of the standard multi-button emulation, is just another reason I hate frameworks. BTW, in the new Hemlock stuff, every time I do a paste, Cocoa likes to add a space after it. Something Gary mentioned a long time ago in an unrelated email. Thank you Cocoa for assuming that I would want a space after a paste, and thanks again for probably not giving me an API way to change it, and thanks again for not making it open source so I can fix it myself, and thanks again for using obj-c, because if it was CLOS I could use method combination to fix it even if it was close source.

How soon until someone adds the delete the space after paste hack to Hemlock and how soon before Apple changes the behavior of Cocoa and we need to take the fix out?

I vote we switch to Carbon so we can prevent my suicide over framework junk like this. Perhaps I could deal with it if it was open source.

I am better now.
*flame off*

Best,

I haven't actually written the little bits of code into the rubix example to check for modifiers on the left-mouse button (the "only" mouse button), and probably won't, because I assume that a large fraction of Apple's consumer population buys real mice.

It now works properly. Left-mouse/drag will rotate the cube, and right-mouse/drag on a face will turn a face clockwise or ccw.
