It only mentions that defvar and > defconst define a symbol as a global variable. >=20 > Could something be written and your comments were very enlightening. If you got to 9.2 then you likely passed through 9 and 9.1. 9.1 tells you about symbol properties, and functions `symbol-name', `symbol-function', and `symbol-plist'. It also tells you about the value cell (but it neglects mentioning function `symbol-value'). 9.3 tells you about obarrays and `symbol-value'. 9.4.1 tells you about getting and setting symbol properties. And so on. `i' in Info is your friend. It has all of these completions for `symbol' in the Elisp manual: symbol symbol components symbol equality symbol evaluation=20 symbol forms symbol function indirection symbol in keymap symbol name hashing=20 symbol property symbol that evaluates to itself symbol with constant value=20 symbol, where defined symbol-file symbol-function symbol-name=20 symbol-plist symbol-value symbolic links symbolic links <1>=20 symbolp symbols-consed And if you have substring completion there are more than twice that number of completions of `symbol'. Another friend: `M-x apropos'. With input `symbol' it shows you a ton of relevant user options, other variables, commands, non-interactive functions, and macros about symbols.
