I ask because as in common "problematic" situation, when you want to separate two (or more) poligons - say, forest from farmland - "/" does not help/work. Not when node selected, nor when entire poligon line.
Huh.

I assume you mean working in Potlatch 2 editor??
When this function does not work there, and you cannot find any hint about special tasks like your separating with Potlatch2 in the OSM wiki, you can also try one of the offline editors like Merkaartor or JOSM. Read also in the OSM wiki how to separate objects with theit help.
If we should help you concretly, give us a permalink to the objects you want to separate, so we also can try to use "/"-key there.

Thank you, Stephan
Yes, I use Pottatch 2. And yes, accessing underneath layers is problem there, sometimes. I'll read OSM wiki and try programs (scripts) you point.
Yes see, as man, who use for 20 years CorelDraw, Adobe Illustrator and (for less years) - Freehand, I knew polygon editing well and have my own way to do it. But those methods are complicated:
select a contour, add two points around problematic one, separate (break) those points from "mother-line", delete resulting shortcut between added points; then you can select underneath polygon, create "parallel", separate this parallel from origin and delete original underneath; while Pottatch 2 hasn't tool for polygon/line expanding/contracting, you will need to correct a path of a resulting line accordingly.
Those operations are not simple and wondering way to do a job. So, thank you once more for pointing me another tools.
And yes, I'll call you for help with permalink, if I'll not found the way to access something. As for now there no any of them in region I am trying to correct, all problems solved by method I describe above.
But I'll go forward, and shit will happen :)

I have no experience of Potlach.
Three years ago I started with JOSM as advised then by experienced contributers.
I suggest you do the same. Once you get the hang of JOSM (ask for advice here)
your editing will be far easier.
There are hundreds of thousands of geometrical errors in the OSM-Database. See
http://tools.geofabrik.de/osmi/?view=geometry
which, if what you say for Potlach is true, can only be corrected with great difficulty using that editor, whereas in JOSM it is, in most cases, very easy.
Another error-check tool is:
http://keepright.ipax.at/report_map.php?db=osm_EU&zoom=14&lat=48.20808&lon=16.37221
It always a good idea to check your work (and that of others in the neighbourhood).
and have fun

thank you, dcp
Your link and experienced help is very useful for me, a new-bee @ OSM. I book marked your links. It seems, it is extremely useful info there: now I see where I must go fist, because I knew those paths in real, many of them I just see from my window - I live on a hill.
Thank you once more, I'll hesitate to call a support from you and community.

Sentence "I'll hesitate to call a support from you and community"
Must to be "I WILL NOT hesitate to call a support from you and community"
Sorry :)
