I created a new sliding panel in gnome, put some "quick launch" icons on it, then tucked it away in the corner. I decided I didn't like the look of the arrow buttons on the hide buttons so I shut them off. Then I decided I didn't like the look of the hide buttons at all so I shut those off too. But it would seem that I screwed myself in doing so as I now have no way to select the panel properties.

I can't get in between the icons, or above them, or below them in order to right click on an empty area of the panel to get it's properties to come back up. Every time I go to properties I end up getting the properties for one of the icons.

I have looked in the keyboard shortcuts in my preferences menu but I didn't see anything that indicated properties.

I've tried holding down ALT and right clicking on the panel hoping it would see through the icons and let me get to the panel properties but it didn't work. I tried various key combinations like that. CTRL, CTRL+ALT, SHIFT, SHIFT+ALT, and so on...

How can I select the panel properties again?
