Keyboard and Mouse

Alt

Pressing the Alt key switches to an alternate GRID. This can typically be a finer grid than the normal one, which allows you to quickly do some fine positioning in a dense area, for instance, where the normal grid might be too coarse. The alternate grid remains active as long as the Alt key is held pressed down.

Ctrl

Pressing the Ctrl key while clicking on the right mouse button toggles between corresponding wire bend styles (only applies to commands that support wire bend styles, like, for instance, WIRE).

The Ctrl key together with the left mouse button controls special functionality of individual commands, like, for instance, selecting an object at its origin with the MOVE command.

Shift

Pressing the Shift key while clicking on the right mouse button reverses the direction in which the wire bend styles are switched through (only applies to commands that support wire bend styles, like, for instance, WIRE).

The Shift key together with the left mouse button controls special functionality of individual commands, like, for instance, deleting a higher level object with the DELETE command.

Esc

Pressing the Esc key when a command is active will cancel the current activity of that command without canceling the entire command (if there is text in the command line, that text will be deleted first, and the next press of the Esc key will act on the command). For the MOVE command, for example, this means that an object that is currently attached to the cursor will be dropped and an other object can be selected.

Crsr-Up/Down

The keys Crsr-Up (cursor up) and Crsr-Down (cursor down) can be used in the command line of an editor window to scroll through the command history.

Function Keys

Function keys can be assigned any commands by using the ASSIGN command.

Left Mouse Button

The left mouse button is generally used to select, draw or place objects.

Center Mouse Button

The center mouse button changes the current layer or mirrors the object currently attached to the mouse cursor.

The following commands support the center mouse button:

ADD	mirror part
ARC	change active layer
CIRCLE	change active layer
COPY	mirror object
INVOKE	mirror gate
LABEL	change active layer
MOVE	mirror object or group
PASTE	mirror group
POLYGON	change active layer
RECT	change active layer
ROUTE	change active layer
SMD	change active layer
TEXT	change active layer
WIRE	change active layer

Click&Drag with the center mouse button will pan the drawing within the editor window. If you want to exceed the range defined by the scrollbars, you can do so by holding down the Shift key while panning.

Right Mouse Button

The right mouse button is mostly used to select a group, rotate objects attached to the mouse cursor, change wire bend styles and several other command specific functions.

The following commands support the right mouse button:

ADD	rotate part
ARC	change direction of arc
BUS	change wire bend
CHANGE	apply change to group
DELETE	delete group
GROUP	close polygon
INVOKE	rotate gate
LABEL	rotate label
MIRROR	mirror group
MOVE	rotate object, select group
NET	change wire bend
PAD	rotate pad
PASTE	rotate group
PIN	rotate pin
POLYGON	change wire bend
RIPUP	ripup group
ROTATE	rotate group
ROUTE	change wire bend
SMD	rotate smd
SPLIT	change wire bend
TEXT	rotate text
WIRE	change wire bend

Mouse Wheel

Inside an editor window the mouse wheel can be used to zoom in and out.
