Delete the portal in game ?

[redskam]

Yesterday i played Portal 2 with a friend. We were doing a test when my cat walked on my keyboard. He must have press a key because my portals have been removed all alone.

After it, i have tried almost all the keys on my keyboard, but portals have not been deleted.

Is there a key to remove portals?

PS: I don't speak English very well, don't look directely the mistakes. :s

No, there isn't. Have you tried resetting your keybinds in options → keyboard + mouse?

Yes i try.
