Editing on a touchscreen

A non-transitory machine-readable storage medium comprising instructions that, when executed by one or more processors of a machine, cause the machine to perform operations comprising:

• determining a position of a guide device on a touchscreen and an axis of the guide device on the touchscreen;
• displaying a first line on the touchscreen parallel to the axis of the guide device on the touchscreen while the touchscreen displays a second line on the touchscreen;
• moving the first line to coincide with the second line in response to a determination that the first line is within a threshold distance of the second line;
• and
• indicating that the second line coincident with the moved first line is selected for potential editing.

A system comprising:

• one or more processors;
• an analysis module that configures at least one processor among the one or more processors to determine a position of a guide device on a touchscreen and an axis of the guide device on the touchscreen;
• and
• an output module that configures at least one processor among the one or more processors to:
• display a first line on the touchscreen parallel to the axis of the guide device on the touchscreen while the touchscreen displays a second line on the touchscreen;
• move the first line to coincide with the second line in response to a determination that the first line is within a threshold distance of the second line;
• and
• indicate that the second line coincident with the moved first line is selected for potential editing.
