Pirate The World - Online Adventure Game

As using keyboard for sailing maybe is usefull to use space or enter or other to select the action like search or attack or dive or shop.

We have that. You can use the space bar or the zero key on the numeric pad.

It will only do one action per space, though, so for example on towns it will only attack.

Might a good suggestion be keys for the other actions, then?

Well, presently, the only space to have multiple actions is a town, and all three of those other actions pretty much need a mouse after you choose them (unless you really like the Tab key).

I just don't see the need for them right now, though thanks for thinking of suggestions!
