This is my new tweak:

(defun open-line-above-and-indent ()
"Insert a new line above the current one maintaining the indentation."
(interactive)
(let ((current-indentation (current-indentation)))
(beginning-of-line)
(open-line 1)
(when (> current-indentation 0)
(indent-to current-indentation))))

(global-set-key (kbd "C-S-o") #'open-line-above-and-indent)

#emacs is great!

In my #emacs adveture of today, I wanted to have something similar to what vim does with the `O` key. Insert a line above the current one. I found that C-o and C-S-o are bound to the same ~(open-line)~ function, which is nearly what I wanted.

#elisp code in the next message :)

@hajovonta Thanks for the respose!

Yep, I did that. But even after executing ~(frame-parameters)~ I don't really get to know which are the available frame parameters. Or even why 'alpha is an alist of two values (95 . 95)

It would be nice to have in the set-frame-parameter function documentation something like a list of parameters, or at least some common parameters like `alpha` and the expected values for them

Sometimes I have difficulties trying to find some information whithin #emacs for specific functions.

i.e. When I do ~(set-frame-parameter nil 'alpha '(95 . 95))~

How can I get more info about the available ~frame-parameter~?

Why are two values in that alist (95 . 95)

I tried with C-h f set-frame-parameter but could not get any valid lead.

I had to do a short presentation at job today and decided to use #Emacs and #orgmode for it.

These are very useful tips https://systemcrafters.net/emacs-tips/presentations-with-org-present/

Thanks @daviwil for sharing!
