Why not ask your question on the new OpenStreetMap Community Forum?

Some streets in my area seem to lack information about the way of traffic and I'm trying to add it. The editor has an icon for such purpose but it only offers one-way options.

How should I proceed?

You don't need to tag a street as two-way. The assumption is that any street without oneway=yes allows travel in either direction, otherwise we'd need millions more tags in the database just to describe the normal situation.

Note that there are a few situations where oneway=yes is implied, and you need to add oneway=no to override that if needed. (See http://wiki.openstreetmap.org/wiki/Link_%28highway%29#Special_considerations_for_motorways) However, renderers have problems with that…

It's important to note that most of the renderers and route generators usually don't have any implied oneway=yes scenarios, though if there's any question, it's a good idea to explicitly tag the implied oneway=yes or oneway=no anyway.

Sometimes ways which are two-way but look one-way are tagged with oneway=no

http://www.openstreetmap.org/browse/way/34152180 is an example of a case where there two parallel two-way motorways tagged with oneway=no and a note explaining that it really is a two-way route, but cases like that are exceptionally rare.
