# Keyboard shortcuts

Hands on the keys — this page is the cheat sheet. Menu items also show their keys.

## Project

File-level basics.

| Key     | Action                        |
| ------- | ----------------------------- |
| **⌘N**  | New project                   |
| **⌘O**  | Open…                         |
| **⌘S**  | Save                          |
| **⇧⌘S** | Save As…                      |
| **⌘W**  | Close project (does not quit) |
| **⌘Q**  | Quit                          |
| **⌘E**  | Export Movie…                 |

Traffic-light close closes the window only — reopen from the Dock.

## Edit

Undo, paste, duration, rotate.

| Key                | Action                                                                    |
| ------------------ | ------------------------------------------------------------------------- |
| **⌘Z** / **⇧⌘Z**   | Undo / Redo (**⌘Y** also Redo when not typing)                            |
| **⌘V** / **⌘C**    | Paste / copy media (plain text while a caption or title field is focused) |
| **⌘⌫**             | Delete selected media or music                                            |
| **⌘D**             | Set Duration…                                                             |
| **⌘1** / **⌘2**    | Set Start Here / Set End Here                                             |
| **⌘]** / **⌘\[**   | Rotate Right / Rotate Left                                                |
| **⇧⌘]** / **⇧⌘\[** | Flip Horizontal / Flip Vertical                                           |

**Edit → Auto Caption N Untitled Slides** and **Edit → Sort by Date Taken** (Oldest First / Newest First / Import Order — no Shuffle) are in the menu. Library calendar and empty-Library right-click add **Shuffle**.

## View

Chrome and zoom.

| Key                      | Action                                                                                                                                                |
| ------------------------ | ----------------------------------------------------------------------------------------------------------------------------------------------------- |
| **⌃⌘S**                  | Toggle Sidebar                                                                                                                                        |
| **⌥⌘I**                  | Show / Hide Inspector                                                                                                                                 |
| **⌥⌘S**                  | Switch Essential / Studio                                                                                                                             |
| **⌥⌘+** / **⌥⌘-**        | Timeline zoom in / out                                                                                                                                |
| **⌘+** / **⌘-** / **⌘0** | Increase / Decrease / Default **UI** text size — app chrome, **Library cards**, and **Timeline** strip height (not Timeline zoom, not slide captions) |

## Playback

Watch without leaving the keyboard.

| Key             | Action                                           |
| --------------- | ------------------------------------------------ |
| **Space**       | Play / Pause (not while a text field is focused) |
| **←** / **→**   | Nudge playhead                                   |
| **⇧←** / **⇧→** | Larger steps                                     |
| **⌘→** / **⌘←** | Next / Previous Slide                            |
| **⌥⌘←**         | Go to Start                                      |

## Help

Docs and diagnostics.

| Key    | Action             |
| ------ | ------------------ |
| **⌘/** | MemoryString Help… |
| **⌘,** | MCP Server         |

**Help → Full Documentation Online** opens this site ([memorystring.codebyz.com](https://memorystring.codebyz.com)) in a browser. In-app Help is the subset that ships in the app; this site is the full public set. **Help → Show Walkthrough** replays the first-run tour. **Help → Report a Problem…** emails a sanitized crash package (stacks, Mac specs, breadcrumbs; no media filenames).

## Tips

Space and arrows pass through while you edit title text. **⌘V** / **⌘C** stay plain text while a caption or title field is focused. Undo/Redo cover most Inspector changes (Style, Motion, Intro, trims, shuffle). Prefer clicking? **Playback → Play / Pause** (Space is not bound on that menu item). **⌘D** applies to every selected slide. **⌘+** / **⌘-** / **⌘0** change UI text size — Library cards and Timeline strip height scale with the same factor; not slide captions.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://memorystring.codebyz.com/more/shortcuts.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
