Settings for WysiwygPlugin that should common to most editor integrations

The global TWiki Variable WYSIWYG_EXCLUDE can be set to make the plugin sensitive to what is in a topic, before allowing it to be edited. You can set it up to veto an edit if the topic contains:

• html - HTML tags (e.g. <div>, not including <br>), or
• variables - simple variables (e.g. %VAR%) or
• calls - TWiki variables with parameters e.g. %VARIABLE{...}%
• pre blocks (<pre>)
• HTML comments (<!-- ... -->)

If you excluded calls in WYSIWYG_EXCLUDE, you can still define a subset of TWiki variables that do not block edits. this is done in the global TWiki variable WYSIWYG_EDITABLE_CALLS, which should be a list of TWiki variable names separated by vertical bars, with no spaces, e.g: * Set WYSIWYG_EDITABLE_CALLS = COMMENT|CALENDAR|INCLUDE

You should set WYSIWYG_EXCLUDE and WYSIWYG_EDITABLE_CALLS in TWikiPreferences, or in WebPreferences for each web.
