There are some commands that as I get more and more familiar with Rstudio I find myself typing again and again.

Keyboard shortcuts are helpful (disclaimer: these mac versions).

  1. Option-Command-i will open a new Rmarkdown code chunk.

  2. Option - is a handy way of typing assignment (<-)

  3. Shift-Command-M is a fast way of adding a pipe (%>%)

A little googling and here is a whole list that I am yet to learn.
