predictive text in ABAP Editor SE38

hello everyone

i've a question on ABAP Editor SE38.

this is my code, which I've learned from an online course:

CLASS flightprogram DEFINITION.

   PUBLIC SECTION.

     TYPES: fi_tab_type TYPE STANDARD TABLE OF spfli.

     DATA: flight_table TYPE fi_tab_type.

   PRIVATE SECTION.

ENDCLASS.

I noticed when the teacher of the online course typed this line: DATA: flight_table TYPE

SAP automatically proposed the type fi_tab_type in the screen tip like in print screen below, and the teacher just press "TAB" or something, and the entire word is pasted.

I'm not sure where to enable this setting. I'm using Front-End Editor (New) which it will auto propose standard SAP codes like CLASS...DEFINITION. PUBLIC SECTION.

Can anyone enlighten me on this?
