[Feature Request] Screen freeze / scroll lock while Claude is generating output

Feature Request

When Claude is actively generating a long response or running multiple tool calls, the terminal output keeps scrolling. There's no way to pause/freeze the screen to read what's already been output without it jumping away.

Proposal

Add a keybinding (e.g. Ctrl+S or similar) that freezes the viewport in place while Claude continues working in the background. Pressing it again (or any key) would resume auto-scrolling to the latest output.

This is similar to terminal scroll lock behavior — output continues to be generated, but the viewport stays put so you can read at your own pace.

Use Case

• Reading a long explanation while Claude is still generating
• Reviewing tool call results mid-stream without losing your place
• Generally keeping your reading position stable during active generation
