Use %EditInsert to set or reset command line insert mode.
%EditInsert may also be entered as %EditIns[ert] or %Ins[ert].
Optional Operands
OPER specifies whether to set, reset, or toggle insert mode.
If OPER is specified as "On" or "Y[es]", insert mode is set on.
If OPER is specified as "Of[f]" or "N[o]", insert mode is set off.
If OPER is specified as "T[oggle]", insert mode is toggled. In other words, if insert mode is currently on, it is set off, and if insert mode is currently off, it is set on.
Default: toggle.
%EditInsert may be invoked without operands by pressing the Insert key.
When insert mode is on, when a character is typed, characters starting at the the cursor column are shifted right, thus allowing the new character to be inserted. When insert mode is off, the typed character is overlaid over the existing character at the cursor location.
