I did so, but each well auto-place removes them. I take it you recommend
ignoring the well spacing DRC warnings until the very end, right?

Well, for me it didn't work that well. I tried it out with a simple layout and
it did
give some very interesting placement hints, but using it on a bigger layout
looks
bad. I think compaction tries to do too much at once, trying to rearrange leads
and
everything. At last I compacted the design manually using a simple algorithm: I
find
horizontal or vertical topological ordering for the nodes and then move them
close
up until I reach DRC limit. I suppose this is far from the idea of compaction
but
worked in this case.

I am afraid that is not the case. The place and size is alright, but the labels
are not drawn in the same way on screen as they are on paper: on screen they
are
printed on top of everything whereas on paper they are _below_. This may happen
because I use the ghostscript filter for printing since there is no native PS
printer around. GS renders the .ps file on screen and the occlusion of labels
can be seen clearly on screen.

Sorry for not knowing the electric glossary. I guess I wanted to ask if it is
possible to define keyboard macros.
