I'm using platuml-mode
on GNU Emacs 25.0.50.1 (x86_64-w64-mingw32). After executing M-x plantuml-complete-symbol
RET it displays a hint in the minibuffer:
You can run the command `plantuml-complete-symbol' with M-x pl-c RET
What does the pl-c keystrokes mean? How to perform it in order to get the plantuml-complete-symbol
command run instead of invoking it from the minibuffer?
