One timesaver I have noted for my workflow is that I can ignore capitalization when referring to account names.
For example, I can have an account named
Liabilities:Acme
However, hledger commands don’t require me to match the uppercase or lowercase letters. For example, I can type
hledger areg LIABILITIES:acme
hledger areg liabilities:ACME
or even
hledger areg lIaBiLiTiEs:AcMe
No matter which capital and lowercase letters I use when writing the account names, I get the same result from the hledger command. So, to save time, I type all lowercase letters.
