In the new SAP ABAP editor, it’s sort-of possible to remap the keybindings you use. If you’re a regular Emacs user, you often find yourself pressing the wrong key combination accidentally – for instance C-a to go to the beginning of a line, only to find that the new ABAP editor by default respects the regular windows CUA keybindings – so C-a does a “Select All” as it does in many windows programs.
