I would like to use CTRL-N and CTRL-P to select the next or previous entry in the context-sensitive autocompletion menu of Mathematica 11.20 on macOS Sierra (10.12).

The questions

• Emacs key bind on Mathematica Linux
• Move the cursor in a notebook using the keyboard
• Emacs key bind on Mathematica Linux

do not answer this.

I’ve already created the file

❯ ls ~/Library/Mathematica/SystemFiles/FrontEnd/TextResources/Macintosh/ KeyEventTranslations.tr 

by copying the default. I am not sure which entry is responsible for the completion menu. Possibly candidates are

"MoveNext", "MoveNextExpression", "MoveNextLine", "MoveNextPlaceHolder", "MoveNextWord", "NextFunctionTemplate", "SelectNext", "SelectNextExpression", "SelectNextLine", "SelectNextWord",
