in Max 5 I had the very handy (macintosh) Cmd+Shift+M shortcut to open the "Send Message…" window. I used that all the time.
In Max 6 this doesn’t work any more. Is there another (documenter or undocumented…) shortcut performing the same operation?
That was so handy…
I use System Preferences -> Keyboard -> Keyboard Shortcuts. Works very well. For sending message to selected object(s) I use cmd+enter, I also have bindings for changing color, inserting/removing watchpoints and a few other menu commands. Nowadays I can’t imagine patching without those shortcuts (and ToolBox of course).
