Vamoose the Grid - Photoshop Vanishing Point Filter

Ok, this one has had me stumped for forever. Problem is I really needed to solve it. You have used the Vanishing point filter in Photoshop to create a grid then you don't want it any more.. perhaps because you want to show someone how to create the grid. So how do you get rid of it. Delete button? nah! doesn't work. There isn't an option in the filter for deleting the grid and starting over, at least I can't find it. So, what's a gal to do?

Answer is.. BACKSPACE. Who would have thought it, but it works. Click the panel of the grid you want to remove to select it and press Backspace and it is removed (so too are any grids built off this one). So, to remove the entire grid, select the first panel and press Backspace and all the other grids disappear.

Like so much in Photoshop, easy when you know how!
