Aims to resolve #6

Issue

Currently, our AI Chat toggle behavior differs from Cursor editor's implementation. We should align our cmd+] behavior with how Cursor handles double-press cmd+L for consistency across AI-enabled editors.

Current Behavior:

• First press of cmd+] opens the ai chat panel
• Second press of cmd+] does not close the ai chat panel (unless we toggle to the editor)

Expected Behavior:

• Match Cursor editor's double-press pattern:
  • Single press of cmd+] opens the chat panel
  • Quick double press of cmd+] should toggle the chat panel
• This mirrors Cursor's implementation where double-pressing cmd+L toggles their AI chat view

Technical Changes:

const additionalShortcuts = [
    {
        key: 'ctrl+]',
        mac: 'cmd+]',
        command: 'aichat.newchataction',
    },
    // ... other shortcuts
];

• Remove the when clause restriction from aichat.newchataction
• Ensures smooth toggle behavior on repeated keypresses

Reference:

• Cursor Editor's cmd+L double-press behavior serves as the UX benchmark
• This change will provide feature parity with Cursor's chat toggle implementation
