# Shortcuts

Every key and gesture the editor and the toolbar panel answer to.

The editor's **Help** button, the question mark at the foot of the rail on its right edge, opens
this page. The keys are the same on every system; `⌘` is on a Mac and `Ctrl` everywhere else.

## Scanning

| Action                       | How                                                               |
| ---------------------------- | ----------------------------------------------------------------- |

| Capture the picked element   | Click, or `Enter`; `Esc` cancels                                  |

## Crop and marks

A right-click on the stage opens a menu of the same actions, each with its key, and one more:
**Crop to what is on screen**.
