Scrub the links!
buttons after they are selected?
Before you go ahead and remove this line consider this.
These dotted lines can be a huge help for the visually impaired, the color blind and those who navigate by keyboard because the
'focus' of the cursor can easily be followed when pressing the Tab key to go
from button to button. Removing them can be a source of irritation for your
visitors, even if you don't like them (the dotted lines, that is!)
But if you are insiting on removing the line then use this link to get the "link scrubber" extension from Al Sparbers site Project Seven.Com. Just look for the link scrubber extension under the extensions section.
If you are unsure of how to install the extension then go here to find out how!
