Example of live template that I use to generate initial modifier parameter using composable function

1. Open live templates settings by double-Shift and entering Live template.
2. Add template group, for example _Custom
3. Add live template with next settings:

• Abbreviation: mom
• Applicable context: Expression
• Description: Modifier

Template text:

modifier = Modifier
    .

To use, put cursor between ( and ) when call composable function, type mom and click Tab
