I'm rubbish at cryptic crosswords but I've been following the answers here (that provide parsing for clues) for many years now and I'm just beginning to make some sense of it all.
As I see it, people with loads of experience in solving cryptic crosswords will recognise familiar indicators (such as 'confused', for an anagram) from past experience. For others though (and even for experienced puzzlers where an indicator is a rare one) it's simply a matter of trying to work out if a particular word could be an indicator of some sort. (e.g. if one sees "brought up" in a down clue, it could well be a very big hint that reversal is involved).
Unless you've got a particularly good memory, looking at long lists of indicators is unlikely to help
directly with learning them but it might well help to gain an understanding of the way that they work. I therefore offer you this excellent link for your consideration:
