Autocomplete
TeXiFy supports autocomplete of labels, many common commands, user defined commands, and (user defined) environments.
This includes for example commands you defined with the xparse package.
If you are looking for a 'dumb' autocompletion mode to autocomplete on any word in the file/project, you can use Hippie completion: https://www.jetbrains.com/go/guide/tips/cyclic-expand-word/ and https://www.jetbrains.com/help/idea/auto-completing-code.html#hippie_completion
Since b0.6.9
When invoking autocomplete on a command or environment that takes required parameters, TeXiFy will insert a brace pair for each parameter. The caret is placed in the first pair, and you can use Tab to skip to the next pair. Since optional parameters are, well, optional, both the command with and without the optional parameters appear in the autocomplete list. If you always select the version with optional parameters, after a couple of times IntelliJ will remember your choice and show it first (so above the version without optional parameters).
