Description

Issue Description

The chat input field in the JetBrains IDE plugin does not support certain keyboard shortcuts and navigation combinations that are commonly used in the IDE.

Current Behavior

The following keyboard shortcuts are not working in the chat input field:

• Ctrl+Shift+↑ (line selection)
• Navigation to line start/end
• Other standard IDE text editing shortcuts

Expected Behavior

The chat input field should support the same keyboard shortcuts and text navigation features as other text editing areas in the IDE.

Technical Context

This issue might be related to WebView implementation limitations, as similar plugins using WebView for their UI components have reported comparable keyboard shortcut issues.
