GNU/Linux Desktop Survival Guide

After cutting or copying a widget the Edit-->Paste menu item (and its Ctl+V keyboard shortcut) will place that widget onto the canvas to replace whatever is currently selected. This may mean that a currently selected widget will be replaced by the pasted widget. To avoid this ensure that what is currently selected is an empty place holder.
What is actually pasted at any time depends on what is selected in the clipboard. By default the most recently cut or copied widget is selected in the clipboard. You can change the selected widget in the clipboard simply by clicking on it.
