Once a component is on the board, you can still move it to a new position, but you have to drag it
using the right mouse button. Alternatively -- if you have a one-button mouse, for example -- you
can drag a component by holding down the control key as you first press the mouse button on it.
You can delete components and wires that you've added by mistake. Just click on the component
or wire to hilite it. Then click on the "Delete" button at the bottom of the applet. The hilited item
will be deleted from the circuit board. If you delete a component that has wires attached, the
attached wires will also be deleted along with the component.

mind. You can click on the "Undo" button to undo one operation. Only the most recent operation
can be undone in this way.
There is one shortcut that you might find useful, if you like using Tacks. You can insert a Tack
