Hi IOhannes

I think those additions are immensely useful. Thanks a lot for porting
them and thanks to Jonathan and Ivica for implementing them (I hope I
thanked all persons involved, and would like to include those that I
didn't know about).

Cool.  A shortcut is often quicker than finding the right spot with the

Also very nice. Though it's odd that you can employ a shortcut when
creating a single connection, but you need to manually make the
connection when the end result should be many connections. Can shortcut
and multiple connections be combined somehow?

Hm... now this makes my above point mute, since obviously for <ctrl>-k
to work you need to select both ends. But I like how you can do
different things with different kinds of selections. So maybe combining
  multi-connect with shortcut is not such good idea after all.

I noticed that <ctrl>-z only removes the manually created link when
creating many links simultaneously. Definitely not a serious issue, but
still deserves to be mentioned.

I truly hope this makes it into Pd. My local Pd will have it built-in
as long as it doesn't break. This improves my patching  work-flow
dramatically while having (almost) no side effect (the one I can think
of is spending a shortcut, which is certainly well spent).  

This feature request is only loosely related: Call me an OCD patient,
but I spend quite some time on getting all the patch chords straight.
This would be so much easier if objects would snap into an invisible
grid of 10x10 pixels. When not creating GUIs, there is no point in
placing objects at pixel-exact positions. Ideally, snap-to-grid could
be turned on and off by shortcut or menu.
