-### Issues bots
-
-[@twbs-lmvtfy](https://github.com/twbs-lmvtfy) is a Bootstrap bot that hangs out in our GitHub issue tracker and automatically checks for HTML validation errors in live examples (e.g. jsFiddles, JS Bins, Bootplys, Plunks, CodePens, etc.) posted in issue comments. If it finds any errors, it will post a follow-up comment on the issue and point out the errors. If this happens with an example you've posted, please fix the errors and post an updated live example. If you opened a bug report, please check whether the bug still occurs with your revised, valid live example. If the bug no longer occurs, it was probably due to your invalid HTML rather than something in Bootstrap and we'd appreciate it if you could close out the GitHub issue.

Instead, use [`$().trigger(eventType, ...)`](https://api.jquery.com/trigger/) or [`$().on(eventType, ...)`](https://api.jquery.com/on/), depending on whether you're firing an event or listening for an event. (For example, `$().trigger('focus')` or `$().on('focus', function (event) { /* handle focus event */ })`) We do this to be compatible with custom builds of jQuery where the event aliases module has been excluded.
