1 Create nodes

click create a sharp node
- If no path is being created, this starts a new path.
Shift+click add to selected path
- If a path is selected, Shift+clicking anywhere starts a new subpath instead of a new independent path.
mouse drag create a bezier node with two handles
Shift+mouse drag move only one handle
- This moves only one handle (instead of both) while creating a node, making it cusp.
Ctrl+mouse drag snap the handle to angle steps
- The default angle step is 15 degrees.

Move last node

- These commands move the last created node (at the start of the red segment) while creating a path.
arrows move last node by the nudge distance
Shift+arrows move last node by 10x nudge distance
- The default nudge distance is 2 px (SVG pixel units, not screen pixels).
Alt+arrows move last node by 1 pixel
Alt+Shift+arrows move last node by 10 pixels
- The actual distance for pixel movements depends on zoom level. Zoom in for finer movement.

Create/modify segments

Ctrl+ snap last segment to angle steps
- This snaps the new node's angle, relative to the previous node, to angle steps (default 15 degrees).
Shift+L make last segment line
Shift+U make last segment curve
- These commands change the last (red) segment of the path to straight line or curve.

Create dots

Ctrl+click create a dot
- This creates a small circle. Its size (relative to the current stroke width) can be set in Preferences.
Shift+Ctrl+click create a double-sized dot
Alt+Ctrl+click create a random-sized dot

2 Finish

Enter finish current line
right click finish current line
clickclick finish current line
- Enter, right click, or double left click finish the current line, discarding the last unfinished (red) segment.
