The ()[]{} match manager is in parenmatch.py. It imports Hyperparser, which uses pyparse.Parser. When one types a closer, the corresponding opener is also highlighted and, depending on the configured style, everything in between. Very handy for showing when enough closers have been typed. Edit => Show surrounding parens, ^0 on Windows, which is essentially ^) on US keyboards, highlights out to the nearest pair. One can select one end of a pair by putting the cursor just inside a fence char. (A tk Text cursor is between characters, not on.)
I don't think I would like automatic flashes when merely moving the cursor, or maybe I don't understand what you propose.
On the hand, moving to the nearest opener to the left or closer to the right could be useful. ^] is already used for indent region, but ^{ and ^} (control-shift-bracket) are available and mnemonic. What shortcuts do you know of?
