You are, of course, free to visit the other part of the Lexicon, the Dictionary.

When you put a lot of these abbreviations on a home drawing, it is good practice to send along a sheet identifying all the abbreviations you used.  That sheet is appropriately identified as a "Key"  or "Legend" or even simply "Abbreviations."
