Emacs: Show Function Documentation

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

🟢 TIP: when you call it and cannot find it, it may be because the Symbol is a variable and not a function. You want to use describe-variable instead. 〔see Emacs: Show Variable Value and Doc

Alt+x describe-command
Show a command's inline doc.

Like describe-function, but exclude functions that cannot be called interactively.
