Using the Mouse in Concept

This section describes the various ways that Concept uses mouse button functions, assuming you use a right-handed mouse.

Left Mouse Button

Use the left mouse button to operate on individual items, and to start and terminate wires at the nearest grid intersection. For example, if you want to terminate a wire at the nearest grid point in the schematic, use the left mouse button.

Middle Mouse Button

Use the middle mouse button to operate on groups, and to modify the action of the Wire and Add commands. For example, pressing the middle mouse button while the Wire command is active causes the wire to route directly, instead of orthogonally. In the case of the Add command, the middle mouse button adds the object to rotate.

Using the middle mouse button on a group of selected objects performs an operation on the entire group, not just the nearest individual object. For example, if you use Select to highlight several objects, and then select Delete, the middle mouse button deletes the entire highlighted group.

Right Mouse Button

Use this button to attach wires to the nearest pin or wire (as opposed to the left mouse button, which attaches to the nearest grid point).The right mouse button also pans across the schematic if held down while moving the mouse.

Strokes

Use the left or middle mouse button to perform actions known as strokes. You can use strokes as shortcuts to perform common tasks. Perform a stroke by pressing and holding the middle mouse button while moving the mouse to draw a line with a specific shape. When applicable, this tutorial uses strokes. You can view all the default strokes in the Stroke Editor by entering the following at the UNIX prompt.

Selecting Commands from the Menu Bar

Use the left mouse button to select commands from the menu bar at the left of the screen (the Command Menu).

Entering Commands from the Keyboard

You can type commands in the Concept Message Window. Find the Message Window at the bottom of the screen. For example, open a schematic sheet by typing the command “edit sheet_name” in the window.

Cancelling Commands

When you select a command, it highlights in the Command Window and echoes to the Message Window. You can cancel commands by selecting the “;” button in the Command Window, typing “;” in the Message Window, or selecting a new command.

Manipulating the Screen

To zoom in on a specific area of the screen, select the Zoom command in the Command Window, and use the mouse to create a box around the area you want to zoom on.To view the entire schematic, press F2 or enter the stroke shape “W.” You can also perform the command by entering “zoom fit” in the Message Window.

Saving a Design Directory

To save the current logic or body drawing, select File Write in the Command Menu. Alternatively, you can enter “wr” or “write” in the Concept Message Window at the bottom of the Concept screen.

Quitting Concept

To exit out of Concept, select File Quit in the Command Menu.
