! Example
! Examples
If you wanted to change the field //myconfig// of the tiddler //AppSettings//, you could use an EditTextWidget to edit the field, and then show the result anywhere else by using `{{AppSettings!!myconfig}}`. Note that this will create tiddler AppSettings if it doesn't already exist.

!! Text Selection
If the edit field already contains text or a default value is provided, you can use the `focusSelectFromStart` and `focusSelectFromEnd` attributes to only select part of the text when using `focus="yes"`.
Partial selection when editing this tiddler's //caption// field:
<$macrocall $name=".example" n="2"
eg="""<$edit-text tiddler=<<currentTiddler>> field="caption" focus="yes" focusSelectFromStart="5" />

!!! {{!!heading}}
Provide a dated heading for this example where only the placeholder (but not the date) is selected for easier text input:
<$macrocall $name=".example" n="3"
eg="""<$edit-text tiddler=<<currentTiddler>> field="heading" size="25" focus="yes" focusSelectFromEnd="13" default={{{ [[Heading Text (]] [<now YYYY-0MM-0DD>] [[)]] +[join[]] }}} />
