click | Create a sharp node |
If no path is being created, this starts a new path.
If a path is selected, 
-clicking anywhere starts a new subpath.
This moves only one handle (instead of both) while creating a node, making it cusp.
These commands move the most recently created node (at the start of the red segment) while creating a path.
The default nudge distance is 2 px units.
This snaps the new node’s angle, relative to the previous node, to angle steps.
These commands change the last (red) segment of the path to a straight line or curve.
These shortcuts only work in the Straight lines or Paraxial modes of the tool.
This creates a small circle whose size (relative to the current stroke width) can be set in Inkscape Preferences.
