+## Auto postings
 
-Transaction modifier rules, AKA auto posting rules, describe changes to be applied automatically to certain matched transactions.
-Currently just one kind of change is possible - adding extra postings, which we call "automated postings" or just "auto postings".
-These rules become active when you use the `--auto` flag.

-A transaction modifier rule looks much like a normal transaction

-(mnemonic: `=` suggests matching).

-- a multiplier with a commodity symbol, eg `*$2` (a star, number N, and symbol S). The matched posting's amount will be multiplied by N, and its commodity symbol will be replaced with S.
