API EditBox HighlightText

Selects text in an EditBox.
 EditBox:HighlightText([start, [end]])
== Arguments ==
;start : Number - the position at which to start the highlight; defaults to 0 if not specified.
;end : Number - the position at which to stop the highlight; defaults to the end of the string if not specified. Indices use standard Lua semantics, so -1 is the end of the string.
== Details ==
* The position before the first character is 0.
* Leaving out both parameters, as in EditBox:HighlightText(), will highlight the entire EditBox content.
== Examples ==
editbox:HighlightText() -- highlights entire content
editbox:HighlightText(0,-1) -- also entire content
editbox:HighlightText(0,0) -- removes highlighting
