Great article! Thank you so much.

What is the difference between cmd + Shift + A on Mac and ctrl + i on mac? Both can be used to align codes, right?

Thanks for your comment Eyayaw.

I just tried on my computer, cmd + shift + A reformats the code following the guidelines. However, ctrl + I does nothing on my side.

What does this shortcut do on your side?

The shortcut does alignment: for example ctrl + i change this code

function(x) {format(x, digits = 2, big.mark = ",") }

into

function(x) {format(x, digits = 2, big.mark = ",") }

Interesting.

I tried with the code you provided, nothing changes when I use ctrl + I. When I use cmd + Shift + A, the code is well formatted, as expected.

Anyway, if on your side you see the exact same result with both shortcuts, then you can choose which one to use :)

Hope it helps!

I don't know why but it does some alignment on my Mac.

In fact what it does is "reindents line" (https://support.rstudio.com...).

Thank you for the replies. Have a good one.

Thanks for the link. If I understand well, cmd + I on Mac reindents line only. So it seems to me that it does not do anything else, for instance adding white spaces, etc.

Cmd + Shift + A reindents line in addition to other formatting rules.

True. I was not satisfied with ctrl + i to begin with, glad I discovered the trick today thanks to you.
