[FEATURE]: autocomplete for other terms #6221
Description
Feature hasn't been suggested before.
- I have verified this feature I'm about to request hasn't been suggested before.
Describe the enhancement you want to request
When discussing code, I'd love it if opencode had a memory of existing terms mentioned inside backticks, by myself and the LLM. I have some long variable names that I want to be clear about, and having backtick auto completion for things already discussed would help speed this up so much.
