How to style a map key

Describe the bug

I have a yaml which has a map with quoted keys. I would like to add new key-value pairs to the yaml with double quoted keys.
I went through https://mikefarah.gitbook.io/yq/operators/style#set-double-quote-style but it either offers to double quote only values or both keys and values. In the yaml that i am operating they keys are double quoted but the values are not.

Input Yaml
Concise yaml document(s) (as simple as possible to show the bug, please keep it to 10 lines or less)
data1.yml:

features:
  "f1": true
  "f2": true

What i want to add is another key: "f3" to the map with value true (without any quotes). Is that possible?

Yep - you can use the "key" operator to work with the key of a map. To set the style of the key you can:

.features.f3 | key style |= "double"

This can be put together with assigning the value true using with

'with(.features.f3; . = true | key style= "double")'

• with changed the context to .feaures.f3
• . = true, the . refers to the current node, which is the value
• key style= "double", key will get the key node of the value, style= will update the style

Hope that makes sense!
