How to use the Option+Space shortcut in ChatGPT on Mac: chatgpt option space shortcut mac

What Option+Space does in ChatGPT on Mac

Option+Space opens a small ChatGPT window that floats above whatever you are doing. You can ask a question, paste some text or start a new chat without leaving the app you are in. The key works from any app, so you do not need to switch to ChatGPT first.

There is one rule that trips people up. The shortcut only works while ChatGPT is running. A global shortcut needs the app open before it can respond. Quit ChatGPT and Option+Space does nothing. UseMacApps and the Mac Install Guide both describe this behavior.

Think of the shortcut as two parts. The key is the trigger. The ChatGPT app is what answers. If the app is closed, you get no window, even when your keyboard works fine.

Which window opens depends on your ChatGPT version

ChatGPT now comes in two Mac apps, and they treat this key differently. In July 2026, OpenAI introduced a new desktop app that brings Chat, Work and Codex together. The earlier app was renamed ChatGPT Classic, and OpenAI says it still gets support.

In the new unified app, Option+Space opens Mini by default. Mini is a floating panel. In ChatGPT Classic, the same key opens the older Chat Bar. The new app does not use the Chat Bar on this key, according to the SpotAsk guide.

A news report says OpenAI will discontinue ChatGPT Classic on January 30, 2027. That report cites 9to5Mac and an OpenAI release notes page. Check OpenAI's own release notes before you plan around that date.

Raycast and Google's Gemini Mac app both default to Option+Space, according to UseMacApps. If either one is installed, it may take the key before ChatGPT does. A conflict like this fails silently, so you may not see an error.

Step by step: open Mini in ChatGPT on Mac

The steps below cover the full path. Most people need only the first two, which launch the app and press the key. Work through the rest when the window does not appear, or when you want a different key.

A one-minute test to confirm the shortcut works

Open a document in TextEdit, which ships with macOS. Click into the text so the cursor blinks. Press Option+Space. If the ChatGPT window appears, type a short question, such as Summarize my last sentence, and press Return.

Now quit ChatGPT with ⌘ Q and press Option+Space again. Nothing should appear. Open ChatGPT, then press the key once more. That two-part check shows that both the key and the app are doing their jobs.

Mistakes that stop Option+Space from working in ChatGPT

• Pressing the key with ChatGPT quit. Launch the app first, then press Option+Space.
• Assuming Option+Space is free. Raycast and Gemini both default to it.
• Mixing up the two apps. The new app shows Mini, and ChatGPT Classic shows the Chat Bar.
• Changing the key in one app and expecting the other to match. Each app keeps its own settings.
• Ignoring your keyboard layout. Apple says shortcut labels can vary by language and layout, so check the menu bar for the right key.

Each of these mistakes takes a minute to check. Start with the app check, then move to the conflict check. Skipping ahead wastes time.

How to change the Option+Space shortcut in ChatGPT Settings

Open ChatGPT, then choose ChatGPT > Settings > Keyboard shortcuts. Find the row named Show Mini and change its key. SpotAsk's guide gives this exact path. The Mac Install Guide says you can change the shortcut in the app's settings, but it gives no click path.

Labels move between builds. One guide mentions Settings > Mini & Pets instead of Keyboard shortcuts. If you do not see the row you expect, scan each Settings section for words like Mini, Keyboard or Shortcut.

Pick a combination that no other app uses. Option plus a letter is a common choice, but it can clash with characters you type. Test the new key in a text field before you rely on it.

What to do when the Show Mini row is missing

Some people cannot find the Show Mini row at all. SpotAsk reports that the entry is missing in ChatGPT builds 26.924 and later, tracked as issue #48756. The guide says that issue was still open as of October 27, 2026.

One developer post suggests editing ~/.codex/keybindings.json by hand, because it reports no settings option. This route is unverified. Back up the file before you change anything, and skip it if editing a text file feels risky.

If the row is missing, update ChatGPT first, then check Settings again. If it is still missing, use ChatGPT Classic for the Chat Bar until the new build shows the setting.

Fix conflicts with Raycast, Alfred and Gemini

A conflict happens when two apps claim the same key. macOS can give the key to only one of them. The other app goes quiet, and you see no error. The SpotAsk guide names Raycast, Alfred and Gemini as likely claimants.

Start with the system check. Open Apple menu, then System Settings > Keyboard > Keyboard Shortcuts. A warning icon appears next to conflicting shortcuts. Double-click the shortcut, press the new key combination, and test again. Apple's guide describes the same steps.

Then check the other apps. Quit Raycast or Gemini while you test. If you want to keep both apps, move one of them to a different key in its own settings. That keeps both tools working.

Keep ChatGPT running and allowed to start

The shortcut can stop working even when nothing conflicts. Two settings matter here. The first is Login Items. On newer macOS, open System Settings > General > Login Items & Extensions and add ChatGPT. On macOS 14, the pane is simply called Login Items.

The second is Accessibility. Open System Settings > Privacy & Security > Accessibility and confirm that ChatGPT is on. UseMacApps lists this pane among its fixes, so check it when the key stops working after an update.

Which Macs and macOS versions work

The current ChatGPT desktop app needs macOS 14 Sonoma or later. UseMacApps says it runs on Apple silicon (M1 or better) or Intel. The Mac Install Guide and OpenNavo say Apple silicon only, so the sources disagree on Intel.

To check your macOS version, open the Apple menu and choose About This Mac. ChatGPT Classic has the same macOS 14 floor, and OpenNavo says it requires Apple silicon. If you use an Intel Mac, test the app before you rely on it.

Why the settings keep changing

ChatGPT is a large product. OpenAI reported 900 million weekly active users and 50 million paying subscribers on February 27, 2026, according to TechCrunch. A product that size changes often. Expect Settings labels to shift, and check your build before you follow an old guide.

Where to go next

If the shortcut works, use it for quick questions and leave the settings alone. For a fuller comparison of the ChatGPT app with other options, read ChatGPT on Mac compared. For the screen and voice side of ChatGPT, read ChatGPT voice on Mac and your screen.
