In general: Not all currently used tags are available as presets. Neither in Potlatch or JOSM. It depends on the programmer which presets he implements. If no preset is available you can always enter the tag/value manualy. In Potlatch hit “+” and enter (in case of stairs) “highway” as tag and “steps” as value. In JOSM you can also enter a free tag/value combination.
Have a look at http://wiki.openstreetmap.org/wiki/Map_Features for other combinations used in OSM.
