On your lecture (7:03 minute), you mentioned you created a keyboard shortcut to create columns. I tried to create it using MacOS, but did not work. ChatGt could not help me in locating Markdown shortcuts . I wonder if you could share references as to how to create them. Many thanks. .:::: {.columns}
::: {.column width="50%"}

Hi, Alberto! David says "keyboard shortcut" in the video, but he's actually using a "snippet" in RStudio, which you can find more about here: https://rstudio.github.io/rstudio-extensions/rstudio_snippets.html

Thanks for solving the mystery.

Hi Libby,
I wonder if this is what David created, a function.
skeleton_columns<- function() { cat("::::: {.columns}\n") cat("::: {.column width="50%"}\n") cat(":::\n") cat("::: {.column width="50%"}\n") cat(":::\n") cat("::::\n") }
What is not clear to me is how one can save this function in RStudio and call it upon.

He is using a snippet. If you play it back slowly, you'll see him type ".clm" and hit enter. This is how snippets work. There are many built in to RStudio that you can test now if you like. Try typing "lib" into a script and then wait - you'll see a menu pop up with the
library
snippet. If you hit enter, the snippet materializes where you had typed "lib" before. Here is some more information on snippets: https://dcl-workflow.stanford.edu/rstudio-snippets.htmlAlberto Cabrera

Thank you for solving the puzzle.

Thanks to you I was finally able to replicate David snippet
snippet twocolumn { cat( ":::: {.columns}\n", "\n", "::: {.column width='50%'}\n", "\n", ":::\n", "\n", "::: {.column width='70%'}\n", "\n", ":::\n", "\n", "::::\n", sep = "" ) }
