Editing Action Properties

The Action Properties Editor lets you configure how a specific custom action behaves by adjusting its parameters.

The editor organizes properties into two columns:

ColumnDescription
Property NameSome properties include sub-properties indicated by a + sign. Expand/collapse with the icons or keyboard.
Property ValueDepending on the type: text field, drop-down menu, or a native checkbox for boolean properties. Every text field also shows an Ellipsis (…) button that opens the expanded editor.

Inline editing

Modify values directly in the Value column. Press Enter to save, OK to apply all changes, or Cancel to discard.

Expanded editor

Click the Ellipsis (…) button available on any text field, or press Ctrl+Enter while editing, to open the expanded editor. Ideal for complex strings (file paths, long text).

In the expanded editor, insert dynamic content using the toolbar:

Variables

Insert system or project variables (e.g. %DESTPATH%, %PBLANGID%).

File References

Reference files that will be unpacked during installation.

Line Breaks

Use /$ to insert a carriage-return-line-feed (e.g. Line1/$Line2).
