Emacs: Show Function/Command Documentation

By Xah Lee. Date: . Last updated: .
Alt+x describe-function
Show a function's inline doc. (commands are also functions.)

Note: Some Symbols are variables, not function. e.g. sentence-end-double-space and some symbol can be both function and variable. e.g. buffer-file-name is both function and variable. To lookup variable doc, see Emacs: Show Variable Value, List Variables
