Use the `alias` and `anchor` operators to read and write yaml aliases and anchors. The `explode` operator normalises a yaml file (dereference (or expands) aliases and remove anchor names).
`yq` supports merge aliases (like `<<: *blah`) however this is no longer in the standard yaml spec (1.2) and so `yq` will automatically add the `!!merge` tag to these nodes as it is effectively a custom tag.
`yq` supports merge keys (like `<<: *blah`) from YAML 1.1. These are no longer part of the YAML 1.2 standard, but remain common in practice. Plain `<<:` keys are recognised as merge keys and round-trip as `<<:` without an explicit `!!merge` tag. When the source uses an explicit `!!merge` tag, that is preserved on output. Internally, when `yq` synthesises a `<<` map key (for example during merge operations), it tags the key as `!!merge` rather than `!!str`.
