The Timeline disappeared

While the Timeline was active, I pressed command+W by mistake.
The Timeline disappeared from the screen.
Now I'm not able to activate it by pressing command+3 or through the Window menu,where it appears gray,
What to do to bring it back?

Double click your sequence in the browser.

Command w is close window. So yeah, like Strypes says, just open the window again.
