The '1 Object' command is used to select a single object (or element). After selecting the command, you are prompted to 'Select 1 Object'. Position the cursor on the required element and then press the left mouse button (or <Enter> key) to select it, and the selected element will be highlighted ready for manipulation.
Lines, rectangles and circles with normal line width, are selected by positioning the cursor on the line.
Lines with multi line width are selected by positioning the cursor in the middle of the line.
Rectangles and circles with multi line width are selected by positioning the cursor on the outer edge of the line.
Text is selected by positioning the cursor on any letter.
Library components are selected by positioning the cursor anywhere on the component.
If you choose the same object a second time it is de-selected. If a single element is selected, using the '1 Object' command, then the selection process ends immediately. By using the 'Objects' command, it is possible to select several elements. After identifying the required elements press the right mouse button (or <ESC> key) and the 'Select' menu re-appears. Here you can terminate the selection process, with the right mouse button (or <ESC> key), or you can continue adding more elements to the selection, e.g. with the 'Window' option.
