I have always been annoyed by the inconsistancies between the key/mouse
strokes needed to enter the various primitives in gschem. Some terminated
on a right mouse click, others on a double left mouse click and one only
terminates when you select another operation.

Some times you change modes with the shift key, other times it is the ctrl
key and others require that you hold down one of the mouse buttons.

Could we agree that certain sequences will work for all of the primitives?


I have mapped out the behavior that I see in the latest version with
magnetic disabled. We have 7 primitives and 4 entry modes:


wire
bus
line
path
arc
circle
box


rubberband
manhattan
polar
bezier



WIRE

left mouse starts segment in manhattan mode
holding shift gives reverse manahttan where the x and y lengths swap
holding ctrl goes to rubberband mode
left mouse terminates segment and starts new one
left mouse double click with no movement terminates entry
right mouse terminates entry, unfinished segemnt is lost


BUS

left mouse starts segment in 1/2 manhattan mode where you have x or y but
not both
holding shift does nothing
holding ctrl goes to rubberband mode
left mouse terminates segment and starts new one
left mouse double click does nothing
right mouse doesn't do anything
terminate entry by changing operation



LINE

left mouse starts segment in rubberband mode
holding shift does nothing
holding ctrl goes to 1/2 manhattan mode where you have x or y but not both
left mouse terminates segment and does not start a new one
right mouse doesn't do anything


BOX

left mouse starts segment in double manhattan mode where you have both
normal and reverse manhattan routes to form a box
holding shift does nothing
holding ctrl does nothing
left mouse terminates box
right mouse doesn't do anything


CIRCLE

left mouse starts circle in polar mode by selecting center point
holding shift does nothing
holding ctrl does nothing
left mouse terminates circle
right mouse doesn't do anything


ARC

left mouse starts arc  in 1/8 manhattan mode where you have positive x only
by selecting center point
holding shift does nothing
holding ctrl does nothing
left mouse selects start point and brings up dialog box for # of degrees to
compute end point
right mouse doesn't do anything


PATH

left mouse starts segment in rubberband mode
holding shift does nothing
holding ctrl does nothing
pressing  left mouse switches to bezier mode
left mouse continues path segment and  starts a new one
left mouse double click with no movement terminates entry
right mouse doesn't do anything
closing the polygon terminates entry



Could we agree that a right click should always terminate entry and that
mode shifts occur when any or all of the mode shift are pressed?
