if (e.charCode != '{'.charCodeAt(0) || !e.shiftKey) return; ? Though I'm not sure what the shift is doing there; some keyboard layouts might have that as an unshifted character.

Hrm good point, any higher level API we can tunnel that through?

Dunno, they're adding all sorts of fancy things. Devmo might have something. I think they recommend that you use an unimplemented API, or something silly like that.... 😞

Damn for a second there I thought Devmo was some fancy new API.

value: "\n{\n [[%tabstop:]]\n}": as you can see - space instead of tab. I think value: "\n{\n\t[[%tabstop:]]\n}" is more logical.

It's not meant to put a tab, ko.projects.snippetInsert will take care of that as per your preferences.

Note to those who prefer 1TBS curlies, use the following:
value: " {\n [[%tabstop:]]\n}"
