Electric presumes that Macintosh mice have 1-button, PC mice have 2, and UNIX mice have 2 or 3 (only 2 are used). Therefore, different versions of the mouse commands combine key presses with clicks.

For example, the selection button is used to highlight objects on the display. On systems with 1-button mice (i.e. Macintosh), the selection button is a plain click of the button, but on systems with two or three buttons, the selection button is the left button.

A note to users of the KDE 2.1 window system (Linux/UNIX): The Alt-Left button is used by the window system, and as a result, you may not be able to issue the Special Select button. To disable the window systems use of this button combination, use the KDE control tool, select "Look & Feel", "Window behavior", "Actions" tab. Near the bottom, select "nothing" instead of "default move".

Notes from mouse table:

- 1: "Toggle" implies inversion of the selection, deselecting what is already selected and adding unselected objects.
- 2: "Another" implies cycling through a list of objects that are under the cursor.
- 3: "Special" allows the selection of "Hard-to-Select" objects.
- 4: Defines a rectangular area.
- 5: Defines a rectangular area and zooms into it.
- 6: Same as "Creation" except that it does not connect if over another object. Also used in Technology Editing to make changes.
