Sorry if these are obvious answers, but I searched googled and cannot find what I am looking for.

  • When I have several files opened in split-screen mode, using C-x C-3, how do I close the JUST window that I am currently in and no one else?

  • I am using Ruby and it does not seem to automatically indent my def endcorrectly .. is there a Ruby plugin that will fix this?

  • Is there a command to go to a specific line?

  • How to interpret ruby ​​from emacs?

for Q3), in addition, you may want to know Ch w COMMAND will always show you the key binding for funcion

for Q4), you can run the shell in the buffer, either M-x eshell, or M-x shell, and just run your script.

Using the eshell configuration in [1], you can easily switch between the shell and your script source (by pressing Cz).
