I must confess, I don't get Cocoa bindings. I've used them for user
defaults, and that's it.
My app has a number of NSTextField/slider pairs for inputting numeric
values. I'd like to support having the up and down arrow keys increase/
decrease my values by a set amount, and having shift up/down arrow
increase/decrease by 10x that amount. (much like PhotoShop does.)
I could do this by subclassing NSTextField and adding a new -keyDown
method that handled the up and down arrow keys.The
control:textView:doCommandBySelector method seems like a more elegant
way to make this work. However, I have no clue how to set up key
bindings for my control fields in IB, and can't find any documentation
to explain what I need to do.
In addition to needing some specific guidance on this particular
issue, I'd also like to know a good reference (online or print) that
explains using Cocoa bindings clearly, including working code
examples? Most of the print manuals I use don't cover this subject.
Thanks in advance for any help you can offer.

Duncan Champney
