 Each item in the list of input titles is passed to the subfilter in turn. The subfilter transforms the input titles into the form needed for sorting.

+* "alphanumeric" - treat items as alphanumerics <<.from-version "5.1.24">>

 Note that subfilters should return the same number of items that they are passed. Any missing entries will be treated as zero or the empty string. In particular, when retrieving the value of a field with the [[get Operator]] it is helpful to guard against a missing field value using the [[else Operator]]. For example `[get[myfield]else[default-value]...`.

+|''suffix'' |the `:sort` filter run prefix uses a rich suffix, see below for details |
+|''output''|the sorted result of previous filter runs |
+
+Each input title from previous runs is passed to this run in turn. The filter run transforms the input titles into the form needed for sorting. For example, the filter run `[length[]]` transforms each input title in to the number representing its length, and thus sorts the input titles according to their length.
+
+Note that within the filter run, the "currentTiddler" variable is set to the title of the tiddler being processed. This permits filter runs like `:sort:number[{!!value}divide{!!cost}]` to be used for computation.
+
+The `:sort` filter run prefix uses an extended syntax that allows for multiple suffixes, some of which are required:
+
+```
+:sort:<type>:<flaglist>[...filter run...]
+
+```
+
+* ''type'': Required. Determines how the items are compared and can be any of: ''string'', ''alphanumeric'', ''number'', ''integer'', ''version'' or ''date''.
+* ''flaglist'': comma separated list of the following flags:
+** ''casesensitive'' or ''caseinsensitive'' (required for types `string` and `alphanumeric`).
+** ''reverse'' to invert the order of the filter run (optional).
+
+Note that filter runs used with the `:sort` prefix should return the same number of items that they are passed. Any missing entries will be treated as zero or the empty string. In particular, when retrieving the value of a field with the [[get Operator]] it is helpful to guard against a missing field value using the [[else Operator]]. For example `[get[myfield]else[default-value]...`.

+title: Hidden Setting: HTML Parser Sandbox
+type: text/vnd.tiddlywiki
+
+<<.from-version "5.1.24">> By default, tiddlers with the type `text/html` are displayed in an iframe with the [[sandbox attribute|https://developer.mozilla.org/en-US/docs/Web/HTML/Element/iframe#attr-sandbox]] set to the empty string. This causes all security restrictions to be applied, disabling many features such as JavaScript, downloads and external file references. This is the safest setting.
+
+To globally disable the sandbox, set the tiddler $:/config/HtmlParser/DisableSandbox to `yes`. This will mean that the code in the iframe has full access to TiddlyWiki's internals, which means that a malicious HTML page could exfiltrate data from a private wiki.
+
+To keep the sandbox but control which restrictions are applied, ensure that $:/config/HtmlParser/DisableSandbox is not set to `yes`, and then set $:/config/HtmlParser/SandboxTokens to the desired list of tokens [[from the MDN documentation|https://developer.mozilla.org/en-US/docs/Web/HTML/Element/iframe#attr-sandbox]].
+
+Note that these are global settings. To control the sandboxing on an individual tiddler basis will require a custom `<iframe>` to be used.

+
+; condition-disabled  <<.from-version "5.1.23">>
+: A ''filter'', that allows us to define the "disabled" attribute for buttons. eg: <<disabledFilterExample>>
+:  This condition ''must'' return "no", if the "state tiddler" or "state field" doesn't exist! So there has to be a `else[no]` element in the filter.

+; shortcuts
+: This is the [[Keyboard Shortcut Descriptor]] eg: `((temp-bold))`
+
+<<<
+
+!! Disabled State
+
+You can use any "state tiddler" to define the button disabled state. It's important, that the ''condition-disabled'' field is a ''filter''. For our example we use the `state-disabled` field from tiddler: <<tempBoldDisabled>>
+
+The easiest way to test filters is with the $:/AdvancedSearch : Filter tab
+
+> The temporary "bold button" is disabled: ''"{{{ [<tempBoldDisabled>get[state-disabled]else[no]] }}}"'' ... You can see the button in the editor toolbar if you edit any tiddler!

+
+!! Create Keyboard Shortcuts for New Button
+
+For our ~HowTo we use the ''Keyboard Shortcut Descriptor'': `((temp-bold))`
+
+To create a valid shortcut configuration we need 2 tiddlers: 
+
