Editing Bells, Tabs and Escapes

When using Visual mode to edit files containing Bell, Tab, Esc, many lines are shown with a ?. This indicates that the line contains unprintable characters and cannot be edited in Visual. Lines containing ShiftOut and Shiftin characters might be modified because of the interaction with the terminal or terminal emulator. However, you may specify substitute characters for use in Visual. The trick is to choose a character that is not used for anything else (say ¤, which is typed as Extend-char-G, or Alt-Z G using Reflection for DOS).

  /set vis bell "ß"        {Alt-Z S in Reflection}  /set decimal on; set vis bell '222 {for Qeditmgr file}  /set vis tab "¤"         {Alt-Z G in Reflection}  /set vis esc "¥"         {Alt-Z H in Reflection}  /set vis so "é"  /set vis si "ç"  /set decimal on; set vis esc '186  {for Qeditmgr file}
