Currently, the autocomplete trigger is set to “!!” which on iPhone involves 3 taps. Instead, it would be great if I could put it as an action bar button.
I tried appending using `drafts.append("!!"), but this doesn’t trigger the automation popup, so is there some way that it can be triggered from scripting
There is not such a method. I do plan to add scripting access to your global autocomplete entries at some point, which would allow for action to be able prompt for selection and insert text, but the actual drop-down list appearring will always be tied to typing. You can, of course, change the trigger characters you use if you would like it to be something you find easier to type on the iPhone.
