“resident” selects atoms based on their assigned residue identifiers, which are can be up to four characters long.

resident residue-identifier-pattern
residue residue-identifier-pattern
resid residue-identifier-pattern
resi residue-identifier-pattern
i. residue-identifier-pattern

indicate residue 230
indicate resi 30-40+50-80
select eighties_loop, i. 82-87 

Residue identifiers containing letters are allowed (e.g. 87A, 87B).

The strict macro equivalent is `residue-identifier-pattern/, however the back apostrophe can be omitted in most cases to allow for residue-identifier-pattern/.

indicate `146/
