Customize highlight/selection border style

[peterschussheim]

I'd like to be able to easily customize a theme to add or modify the highlight/selection border style. The high contrast theme provides a very nice dashed border when selecting and highlighting tokens.
It would be great to have this available in user settings so I can use other themes with this border style.

You can't customise the style of the border, but you can chose to also have the same border with the color of your choce by setting the "editor.selectionHighlightBorder"
