Simple question: does anyone know of a shortcut key for commenting in Rmd?
In Knitr this can be done using CTRL + C, which produces in both writing and coding environment a comment line. This does not work in Rmd unfortunately.
At the moment I have to type out:
<!-- Comments -->
I am using R-studio.
回答1:
Add a snippet under the "markdown" section:
(I made mine hcm) then type:
hcmShiftTab and it'll expand to whatever you want (mine was <!-- -->)
You can make the snippet text shorter as well.
I agree with Ben that you could go to RStudio support and ask for a kbd shortcut for this.
