feat: DemoType mode — simulated typing for demos by yusufk · Pull Request #33 · 07JP27/ZoomacIt

yusufk · 2026-05-23T21:31:24Z

Summary

Implements DemoType (⌃⇧D) — simulates typing pre-entered text character-by-character into the focused app. Matches Windows ZoomIt behavior.

Changes

DemoType

Hotkey ⌃⇧D opens input dialog to enter/paste text
Click "Type" → focus returns to previous app → text types out character by character
Press ⌃⇧D again to stop mid-typing
Configurable speed: 5–60 characters/sec (default 15)
Settings tab for pre-configuring text and adjusting speed
Remembers last used text between sessions
Uses CGEvent Unicode key posting (requires Accessibility permission)

Focus Restore (all modes)

Zoom, Live Zoom, Draw, and DemoType now restore focus to the previously active app on dismiss
Matches Windows ZoomIt behavior

Menu Bar

Added Live Zoom and DemoType entries with hotkey shortcuts

Testing

Verified on macOS 15.7.7
Tested: dialog flow, typing into Terminal/TextEdit, speed adjustment, stop mid-type, focus restore

It looks like the branch for another pull request of yours and the branch for this pull request have gotten mixed together.
Please keep each branch scoped so that it reflects only the contents of its own pull request.

Fixed — rebased the branch so it only contains the DemoType commit on top of main. All Live Zoom references have been removed. The branch is now properly scoped to just this feature.

Changes:

Removed Live Zoom hotkey registration, menu item, and controller references
Kept only DemoType-specific code (controller, settings tab, hotkey, menu entry, focus restore)

These branches have been rebased — each now only contains commits scoped to its own feature. Could you take another look?

Pull request overview

Adds a new DemoType mode (simulated typing via ⌃⇧D) and wires it into the app’s hotkey/settings/menu infrastructure, plus introduces “restore focus to previous app” behavior for existing overlay modes.

Changes:

Added DemoType settings (text + characters/sec) persisted in Settings and covered by unit tests.
Registered a new global hotkey and added a DemoType menu bar item.
Introduced DemoTypeController to show an input dialog and post per-character CGEvents; added focus save/restore plumbing in AppDelegate.

・Please update docs/ to reflect this change as well.
・Please check Copilot's review and address it if needed.

Addressed all Copilot review feedback:

✅ Race condition: demoTypeController now assigned before start()
✅ activate() API: Using activate(options: .activateIgnoringOtherApps)
✅ Cancel path: Restores previous app focus on Cancel/empty input
✅ Accessibility check: Added AXIsProcessTrusted() preflight with prompt
✅ Division by zero: Speed clamped to 1–200 range
✅ O(n²) indexing: Using Array(text) for O(1) character access
✅ xcuserdata: Removed from tracking, added to .gitignore
✅ README: Added Accessibility permission note

Not changed:

pbxproj hand-edit — project uses XcodeGen but the generated output is committed per repo convention

Conflicts resolved, docs added, Copilot feedback addressed. Ready for re-review.

Thanks for working on DemoType, but I need to push back here: please verify the actual ZoomIt DemoType behavior before implementing or documenting this as compatible. The current workflow does not match ZoomIt, and this is not a small UX difference.

References:

Official ZoomIt documentation: https://learn.microsoft.com/en-us/sysinternals/downloads/zoomit
Microsoft Sysinternals blog introducing DemoType in ZoomIt v8.0: https://techcommunity.microsoft.com/t5/sysinternals-blog/make-demo-typing-easy-with-demotype-in-zoomit-v8-0/ba-p/4050566

In ZoomIt, pressing Ctrl+7 does not open an input dialog. The DemoType script is prepared ahead of time, either from a configured file or from clipboard text marked with the [start] prefix. Then Ctrl+7 immediately starts injecting the current script/snippet into the already-focused target window.

The current implementation opens a modal input dialog every time Ctrl+7 is pressed. That means the user has to enter or paste text at activation time, click Type, and then rely on focus restoration. This is fundamentally different from ZoomIt's DemoType workflow and makes the feature feel like an ad-hoc typing macro rather than DemoType.

Please re-check the upstream behavior and adjust the implementation accordingly. At minimum, the DemoType hotkey should not open a text input dialog. It should run preconfigured/preloaded DemoType text against the currently focused target app.

ZoomIt-compatible behavior to account for includes:

Ctrl+7 starts typing the prepared script immediately into the focused target window
script can be sourced from settings/file and/or clipboard with [start]
[end] splits the script into snippets
Ctrl+Shift+7 moves back to the previous snippet
Esc cancels an active DemoType session
control keywords such as [pause:n], [enter], [up], [down], [left], [right], and [paste]...[/paste] are supported, or clearly documented as not yet supported

DemoType (⌃⇧D): - Hotkey shows input dialog to enter text - Types text character-by-character into the previously focused app - Configurable speed (5-60 cps, default 15) - Settings tab for pre-configuring text and speed - Remembers last used text Focus restore: - All modes (Zoom, Live Zoom, Draw, DemoType) now restore focus to the previously active app on dismiss Menu bar: - Added Live Zoom and DemoType entries with hotkey shortcuts

- testDefaultDemoTypeHotkey (⌃⇧D) - testDefaultDemoTypeSettings (empty text, 15 cps) - testDemoTypeHotkeyRoundTrip - testDemoTypeTextAndSpeedRoundTrip

…settings UI

- Add Accessibility permission check before CGEvent posting - Assign demoTypeController before start() to avoid race condition - Restore previous app on Cancel/empty input paths - Clamp speed to safe range (1-200) to prevent division by zero - Use Array(text) for O(1) character indexing instead of O(n) String indexing - Use activate(options:) for reliable app activation - Remove xcuserdata from tracking, add to .gitignore

Superseded by #37 — complete rewrite based on actual ZoomIt DemoType behavior (verified against microsoft/PowerToys source code). Addresses all review feedback about branch contamination and behavior verification.
