Undo a single iab abbreviation expansion

Question

Vim has an "abbreviation" feature built-in that can automatically expand certain abbreviations:

:iab SE Stack Exchange

However, sometimes I might want to type "SE" without it expanding to "Stack Exchange."

Is there any way to undo a single abbreviation and insert only the original, unabbreviated text? If not, can I add something to my .vimrc to enable a key shortcut or other method of doing so?

Answer 1

When you typing SE hit CTRL-v and then spacebar to insert space character. See :h i_CTRL-v for details.
