When things go wrong, it is sometimes hard to figure out why. For example, an option might be set in the system vimrc file, in a personal vimrc file, in a plugin (global or local), or interactively. Vim will tell you where the current value was set if you ask:

:verbose set history?

will tell you the current value of the 'history' option, and where it was set.

[edit] Comments

Is there a similar feature for mappings? RedHat ships with a modified vim that sources their own set of maps, and it took me forever to track them down and disable them. This feature for maps would have saved me a lot of trouble.

:scriptnames # list all loaded scripts & their location
:map # list maps
:functions # list functions
:ab # list abbreviations

TODO: It would be nice to:

integrate the comments about mappings, functions, etc in the tip text
change the page title to reflect this evolution.
