This question might be over-answered but I could not find one. Basically I am using RStudio and the keyboard shortcut cmd + shift + c for in
The absolute simplest answer is in the comments on the addins answer above and deserves its own billing (with attribution):
Rstudio does have column selection, to get multiple cursors alt + mouse to select, or ctrl + alt and the arrow keys, then keys move forward and back by words/lines work as expected. – Peter Apr 16 '16 at 23:55
[ETA: On Mac, ctrl + option + arrow keys or option + mouse.]
@Peter nice. in that case you could just make a chunk of cursors at the beginning of the line and and type in #' . I doubt roxygen comments are used enough to warrant a dedicated keyboard shortcut, but it wouldn't hurt to have I guess – rawr Apr 17 '16 at 1:26
