To get the current completion information, |complete_info()| can be used.
Also see the 'infercase' option if you want to adjust the case of the match.
+When inserting a selected candidate word from the |popup-menu|, the part of
+the candidate word that does not match the query is highlighted using
+|hl-ComplMatchIns|. If fuzzy is enabled in 'completopt', highlighting will not
+be applied.

*complete_CTRL-E*
When completion is active you can use CTRL-E to stop it and go back to the
originally typed text. The CTRL-E will not be inserted.
