This isn't exactly what you asked for, it's not a definitive updated list of official keyboard shortcuts, but here's some ones that come to mind.
Flow editor:
You can now navigate the flow with the arrow keys (yay!)
Shift+enter: Opens / closes the parameter pane of a Sound
Capslock+shift+enter: Opens parameter pane in "text" mode allowing ?ParameterVariables to be entered into all fields including check-boxes etc.
Parameter pane:
in a sample / wavetable parameter
shift+click the disk button: get info about the file
cmd or ctrl +click the disk button: open the file in the sample editor
shift + cmd or ctrl +click the disk button: audition the file
VCS:
In a VCS that doesn't fit in the window you can scroll about by shift+ctrl click and drag with the mouse (actually it seems to be shift + cmd, ctrl or alt).
You can discover many keyboard short cuts by looking for them in the menu entries.
DIY shortcuts:
The mac's keyboard settings lets you make keyboard shortcuts for any unique menu item in an application. I would strongly recommend using that to add shortcuts to your favourite commands. The mappings I use are as follows:
As suggested to me by Charlie Norton, I use the "power claw" key combination which is ctrl+alt+cmd, hence forth called The Claw (in a deep menacing voice)!
claw+A: My Custom Prototypes .kym file window
claw+B: Browser (at the root of the disk)
claw+C: Collect
claw+D: DSP window
claw+E: Edit class
claw+H: Unlock VCS for editing (via BetterTouchTool)
claw+I: Set Replaceable Input
claw+J: Describe Sound
claw+K: Browser at kyma's system folder
claw+L: Open large editor window and grow font (via BetterTouchTool, not needed so much now we can set font)
claw+M: Browser at my own kyma Sounds folder
claw+N: New class from example
claw+O: Oscilloscope
claw+P: The prototypes window
claw+R: Remove VCS Layout
claw+S: My default text editing window
claw+U: Clean up
claw+V: Copy contents of current parameter and paste in the next parameter (via BetterTouchTool)
claw+W: My default Working.kym file window
claw+Y: My "why" notebook file - kind of like a todo, it reminds me where I'm at.
claw+Z: Status window
claw+0: My "zero" .kym window. An empty file I use for copying and pasting, useful with many windows open.
also:
shift+cmd S: Save as
shift+cmd R: Virtual control surface
shift+cmd V: Paste special...
shift+claw+R: Record to disk
shift+claw+V: Copy parameter and paste into previous parameter (via BetterTouchTool)
Window sizing and placement:
Using the Moom app I've also got a set of standard window sizes and positions I map to keys like claw+left etc so I can make Kyma's windows tile nicely.
