export ZSH_LLM_SUGGESTION_SERVER="localhost:11434" #configure server
Wipe history with alias wipe='rm ~/.ollama_history'

Can bind keys:

bindkey '^o' zsh_llm_suggestions_ollama
bindkey '^[^o' zsh_llm_suggestions_ollama_explain
bindkey '^p' zsh_llm_suggestions_ollama_freestyle #new freestyle mode allows for querying the LLM without asking for ZSH help
