The edit text widget provides a user interface in the browser for editing text tiddler fields. The editing element is dynamically bound to the underlying tiddler value: changes to the tiddler are instantly reflected, and any edits are instantly propogated.
By default, applying the EditTextWidget to the
text field of a tiddler will generates an HTML
<textarea> element, i.e. a multi-line editor. Applying the EditTextWidget to any other field generates an HTML
<input type="text"> element, a single-line editor. This behaviour can be overridden with the
The content of the
<$edit-text> widget is ignored.

One trap to be aware of is that the edit text widget cannot be used to edit a field of the tiddler that contains it. Each keypress results in the tiddler being re-rendered, which loses the cursor position within the text field.
Instead, place the edit text widget in a template that references the tiddler you want to modify.
For example, if you wanted the tiddler GettingStarted to edit the value of the "myconfig" field of the tiddler "AppSettings", you might do so by creating a separate tiddler "ChangeAppSettings" that contains the following:
<$edit-text tiddler="AppSettings" field="myconfig"/>
And reference the template in any other tiddler (e.g. GettingStarted) with
This works when your use of the tiddler is not the AppSettings itself which would cause a recursion problem. In this latter case you have to save the fields to a temporary (or alternative) tiddler (sort of the reverse of above) like so:
<$edit-text tiddler="StoreAppSettings" field="myconfig"/>
In short the EditTextWidget can not change properties of the tiddler it is embedded in or part of. It can only change fields of other tiddlers. One could use ShadowTiddlers to accomplish the field storage if needed.
