Problem Statement

I often find myself switching to run bash commands in the claude terminal, and it can slow me down that the tab autocomplete I am so used to in my normal zsh shell is not available in the bash mode while using claude.

Proposed Solution

I would like when I am in bash mode, I can tab my way through like I would in a normal shell
