Rstudio pipe operator (%>%) shortcut (Ctrl+Shift+M) not working

Question

Recently the RStudio shortcut for the pipe operator %>% stopped working. This appeared to have occurred randomly, as I didn't update anything. Does anyone know what is going on and how I might fix this?

Answer 1

It appears that many people are having this issue across R and RStudio versions (https://community.rstudio.com/t/ctrl-shift-m-pipe-operator-shortcut-is-suddenly-stop-working-since-this-morning/118362), and may be due to a conflict with the default Ctrl+Shift+M being a shortcut for another process (seems to be "mute" in WebEx for many; see comments and other answers below).

In your RStudio IDE if you go to the "Tools" tab and select "Modify Keyboard Shortcuts..." you can see a list of shortcuts. If you type "pipe" into the search bar at the top, you will see that "Insert Pipe Operator" is still set to Ctrl+Shift+M, yet it does not work.

The simple solution that I chose is to click on this "Ctrl+Shift+M", once highlighted, type in a new shortcut by pressing the keys you would use for that shortcut (although there is likely a more elegant solution than changing your shortcut).

I chose "Ctrl+Shift+," since the comma is only one space away from M on my keyboard.

I am sure it is WebEx after I experimented restart/kill the process of Webex.

edit: after ending the process in the task manager (open task manager, find webex and end process) ctrl+shift+m works again. (Windows 10)

Answer 3

I had the same problem. I suppose it comes from WebEx as mentioned in the comments. I uninstalled WebEx but the problem remained. Then I cleaned Windows registry using the tool in CCleaner software and now the pipe shortcut is working again !
