Problem Statement

Currently you can enable vim mode which provides basic vim functionality: normal and insert mode. Having visual mode supported to select chunks of text would be extremely useful for people whose workflow is pretty vim motions oriented.

Proposed Solution

Visual mode is implement and behaves like vim:

• When typing v you enter visual mode
• When typing V you enter visual mode and select the current line
• When entering, you see VISUAL indicating your mode
• When moving while in visual move, the selected text gets highlighted
• ...

If the cursor would change in different vim modes, it would be great https://github.com/anthropics/claude-code/issues/32469
