expand-look-back - Complete a word by looking back for a similar word
expand-look-back attempts to complete the word at the current position by looking backward for another word which starts the same. If such a word is found within 100 lines of the current cursor position the current partial word is replaced with the word found.
expand-look-back is automatically invoked from the expand-abbrev-handle(3) macro in response to an expansion command, it is only invoked if enabled in the user-setup(3) => General => Abbrev Expansion => Lookbk setting is enabled.
expand-look-back is a macro implemented in abbrev.emf.
The user-setup configuration simply sets the macro variable .expand-look-back.on to TRUE, i.e.:
set-variable .expand-look-back.on 1
It may be subsequently disabled by setting the variable back to 0.
