This section lists all available symbol keys (SKEYs) in alphabetic order. Cross-references are given to the generic component types (GTYPEs) under which the user will find them described in the preceding sections of this appendix (if appropriate).

Each SKEY has an indication of whether or not it may be redefined, as explained in the ISODRAFT User Guide, Section 11.1, The Basic Principles. For components which include spindles, the standard spindle type associated with the predefined SKEY is indicated, refer to ISODRAFT User Guide Section 11.3, Special Keys, for illustrations of these spindle types.
