i was initially confused, why would you want to jump or even convert between the '<' and '>' signs? but from trying it out on that snippet, '%' actually jumps to the nearest bracket and selects(?) the matching one [0].

now, i'm not 100% sure on the exact behaviour, but e.g. even a cursory test in sublime shows it will highlight the start and end brackets if i'm inside the if-expression and you can "expand selection to brackets".
