Keyboard bindings

Key	Description
DEL	Delete path. If the DEL is pressed when cursor is within the viewport then the viewport will be switched off.
a/Shift+a	If no point on the path is pressed, toggle display of angle between first 3 points. Only when a point of the path is pressed, change rotation angle (twist) of cross-sectional ellipse for tube.
c	Toggle connection of the two ends of path - making a closed or open path.
f	Flip two ends of the path.
l	Toggle display of path length.
n	Toggle display of path point numbers.
Shift+l	Toggle display of caption beside the path or on the path. When displaying caption beside the path, the caption text is always displayed at one end of the path. This end can be changed by changing the arrow direction (forward/backward). When displaying caption on the path, the caption text is displayed all along the path. The text is displayed only while in tube mode. The height of the text can be changed by "height" command. The angle of the text can be changed by "angle" command. The direction of the text can be changed by changing the arrow direction (forward/backward).
p	Toggle display of path points as big dots on the path.
s/Shift+s	Only when a point of the path is pressed, change radius S of cross-sectional ellipse for tube.
t	When no point on path is selected, toggle display of path as caption/image/tube or line. If caption is enabled, then caption text is rendered. If image is enabled, then image texture is rendered. If neither is enabled then a tube is drawn. When a point of the path is pressed, change radius T of cross-sectional ellipse for tube.
Shift+t	When no point on path is selected, bring up caption dialog. Caption is enabled. When caption is enabled, pressing t will render caption text instead of tube. When a point of the path is pressed, change radius T of cross-sectional ellipse for tube.
