Shortcut to Deselect

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.

If you use the up or down arrow key to move the cursor, that will deselect everything.

Oh my gosh! Simple so. Thanks a lot
