31.13 Making Cursor Keys Work in vi Text-input Mode

Here is my .exrc file, which I customized for a VT100 terminal. It is set up for C and nroff -me macros. [Strings like ^[OD are set by the cursor keys ( 41.12 ) on VT100-type terminals. Make the ^[ by typing [CTRL-v] [ESC] . Many vi versions make this easier; they understand map #1 ( 31.2 ) to mean "map function key F1." -JP  ]

map! ''  \*(rq

I can use the cursor keys while inputting text. This is handy because I can back up and add text without pressing ESC. [Though you may not be able to ( 31.3 ) undo your previous change with the u command. -JP  ]

Also, I have defined [F1] to append at the end of the line. This is useful because it doesn't matter what mode you are in, it always puts you in text-input mode.

At one time, I mapped the entire numeric keypad to emulate the EDT editor.
