I'm going to give a talk on how wonderful is #emacs in crafting your own tooling for an audience that probably does not even know about emacs. In part I'm inspired by the great #systemcrafters and the crafting spirit. (Thanks @daviwil !)

I have several ideas on how #emacs can empower you to create your own tools, but It would be great if you can give me some ideas to share the joy of emacs.

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!
