The editor is where a capture gets arrows, boxes, text and more. Here is how to open it and what each tool does.

Open the editor#

Press Edit on the card after a capture, click a tile in Recent Captures, or choose Open it in the editor in Settings › Capture to skip the card and go straight in.

The tools#

The tools are down the left side. Press a tool's key to pick it:

ToolKeyWhat it does
SelectVClick a mark to move it, recolour it or delete it
ArrowADrag from the tail to the point
RectangleRA box
EllipseOA circle or oval
LineLA straight line
FreehandPDraw with the pen
TextTClick, type, press Enter to finish
Numbered stepSClick to drop a numbered badge: 1, then 2, then 3
HighlightHHighlight text without hiding it
SpotlightFDrag a box to keep it bright. The rest dims. See spotlight
PixelateBBlurs a region into blocks
RedactECovers a region with solid black
CropCSee crop and rotate

Hold Shift while dragging to keep a shape square or a line at 45 degrees.

Colour and thickness#

A floating bar holds eight colours and a line width slider. Click the slider and the arrow keys move it one step at a time. Changing the colour while a mark is selected recolours that mark. Where each new drawing starts is set in Settings › Images, under Line width.

Marks stay editable#

Your marks are kept as shapes, not pixels, until you save. That means you can still select, move, recolour and delete any of them. (They move, but they don't resize.)

With a mark selected, Esc lets go of it. With nothing selected, Esc closes the editor.

Undo#

⌘ Z undoes, ⌘ ⇧ Z redoes. On Windows it's Ctrl Z and Ctrl Y.
