For instance, I am trying to coble together a fast bash script. The syntax is set to “Shell Script” but when I type stuff it is CONSTANTLY popping up this menu. Consequently if I hit enter at the end of the line it populates what I types with this stuff. I can’t figure out how the heck to turn it off and it’s driving me insane. It’s made the tool unusable at the moment.
Not sure if this would help your issue but I just disabled spellchecking.
In “File” menu > settings > packages, search “spell” to find the spell-check package.
Edit: Just saw another option. Search for the autocomplete-plus package. I recall disabling that one too. Reading up on these may help use them better but, to start with, I just disabled them until I had the time to dig further.
