Emacs: Show Function/Command Documentation
- 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
