are you on the latest version of BashSupport Pro?
1.4.11 should have fixed this.
zsh should automatically trigger the injection and also show up when you call auto completion after the opening fence block.
Does that work for you? If that’s not the case, please pase the info at
Help>About>Ctrl/Cmd+C and paste it here.
Currently only the JetBrains Markdown plugin is supported. Let me know if you’re using something else.
By default, the IDs supported by the Markdown plugin are the names of the languages. “Shell Script” is taken by the JetBrains plugin and “Bash” by legacy BashSupport. I had to pick something else. It might not have been the best choice, though.
