I'm failing to find a button to remove messages from my sreen.
For example, near Firelink there is a tree, which looks like a giant. You can "Examine" it by pressing "A" or it's equivalent for the keyboard, then the message "A seed of the giant is yet to fall" appears, there is "OK" button under it.
I can press it with mouse, but I don't like using mouse. I'm failing to see apropriate option in the key settings in the menu. So what button I should press to make such a message disappear? Idealy tell me where I can find the settings for it in the menu.
