Problem Statement

Problem

After pasting an image into the prompt input, the image appears at the top of the input area. Pressing the up arrow key now navigates to edit/select the pasted image instead of accessing the previous prompt from history.

This creates a UX conflict where after pasting image users lose the ability to cycle back to previous prompts.

Current Behavior

1. Paste an image (Ctrl+V)
2. Image appears at top of input area
3. Press up arrow → cursor moves to the pasted image
4. Cannot access previous prompt history with up arrow

Environment

• Claude Code version: 2.0.73
• Platform: macOS
• This appears to be a recent change in behavior

Proposed Solution

I would like shift+up arrow to up arrow into the images, and preserve the up arrow for going back to previous prompts. Same with the down arrow.
