pipe %>% keybinding in personal keymap.cson file

[TidyStewart]

Hi, I am trying to create a keybinding. I want ctrl-5 to map to the following keystrokes %>% which is the pipe operator that I use all the time when doing data analytics in R / Tidyverse. I have put this in my keymap.cson file:

'pipe':
'ctrl-5': 'editor:%>%'

But it is not working. Grateful for any help. Thanks!
