Some actions can be accessed using mouse gestures. Mouse gestures are performed by clicking and dragging the middle mouse button. Gestures are not normally enabled; to enable them, you need to add:

(middle-button "stroke")

to a gschem configuration file.

By default, the following gestures are available:

• Draw a “Z” to begin drawing a region of interest box to zoom to, like View→Zoom Box (see Viewing schematics).
• Draw a line upwards to zoom out.
• Draw a line downwards to zoom in.
• Draw a “S” to return to Select Mode (see Selecting objects).
• Draw a “C” to copy selected objects, like Edit→Copy Mode (see Moving and copying).
• Draw a “M” to move selected objects, like Edit→Move Mode (see Moving and copying).
• Draw an “E” to edit selected objects, like Edit→Edit.
• Draw a “D” to delete selected objects, like Edit→Delete.
• Draw an “L” to begin adding lines.
• Draw an “N” to begin adding nets.

To modify or add to the available gestures, please see examples in the gschem system configuration file.
