Contrary to airdrops where the tokens are automatically dropped to your account, airgrab means that you have to manually go and claim your tokens.
The Airgrab Tokens page displays the following;
Token - Symbol for token
Name - Full name of token
Account - The account the tokens are sent from
Airgrab - Status of Airgrab (Airgrab/Already Grabbed)
You can click the button to AIRGRAB ALL TOKENS or Airgrab individual tokens one at a time by clicking the button under the "Airgrab" column on the far right.
