Shortcut to Deselect

Hello,
Somebody know the shortcut in Toad For Oracle, to deselect the SQL selected ?

Every hour i have that click in windows to deselect.

With the command CTRL+A, I select all lines. I need the inverse command. If is that exist this shortcut

Thanks for attention.

Wrong forum once again - you need to post on the toad for oracle forum. This is just the oracle without any Dell product forum …

Do explore product, choose toad for oracle, then choose forum …

Sorry once again…
