Hm, is it particularly more distracting than when moving the cursor?  But permanent highlighting sounds interesting… something like the “focus” highlighting in Xcode, perhaps?  (For anyone who hasn’t seen it, that dims the outermost scope slightly, and the next outermost scope slightly more, and so on. There’s a picture here: http://apple.stackexchange.com/questions/75745/xcode-4-key-binding-for-focus-code-blocks-on-hover ) It makes it easy to identify the entire block rather than a single character, and without distractions. I’d definitely appreciate a feature like that.


Anyway, if you really want a closing brace to flash its opening mate, a slightly ugly hack is to make a shortcut to type “}” followed by a left-arrow and a right-arrow. A Textmate macro won't quite work, presumably since you’re not actually pressing the right-arrow key, but you can program the amazing Karabiner (https://pqrs.org/osx/karabiner) to do it by adding this to its private.xml:

  <item>
    <name>Textmate Brace Closer</name>
    <appendix>Turn "}" into  }←→ to flash the opening brace</appendix>
    <identifier>private.bracer</identifier>    
    
	<appdef>
	  <appname>TEXTMATE</appname><equal>com.macromates.TextMate.preview</equal>
	</appdef>
    <only>TEXTMATE</only>
	
    <autogen>--KeyToKey-- KeyCode::BRACKET_RIGHT, MODIFIERFLAG_EITHER_LEFT_OR_RIGHT_SHIFT,  KeyCode::BRACKET_RIGHT, ModifierFlag::SHIFT_L, KeyCode::CURSOR_LEFT, KeyCode::CURSOR_RIGHT</autogen>
  </item>
