I'm having a problem with what seems to be a feature of tinymce (but I can't find documentation on it). When I type '#foo', follow by a newline it creates a h1 with the text 'foo'. I discovered that when I use 2 hashtags it creates an h2, 3 hashtags and h3, ...
The problem is I'm using keywords like '#foo#' to be replaced by certain values, and now these are getting replaced by h1 accidentally.
Anyone got a clue on how I can stop tinymce from doing this?
This behaviour is caused by the textpattern plugin. It uses markdown like settings to make editing easier. You can disable this plugin or reconfigure it.
