Cannot remove a widget

[Wayne Davis]

Kubuntu 12.10

I installed a  timer widget from the widget download repository link.  
"TIMER" by Davide Bettio

I cannot UN-INSTALL it. there is no un-install button.   Arrrgghh


I did search the web, and found similar instructions. but they do not 
pertain to 12.10 were not 'close enough' to provide a solution.

I would guess that if I knew WHERE it is, that would be most of what I 
need.  But I do not know what to look for.

Suggestions?

TIA
