Description of the Issue

I try to add a macro to set the "virtual space" options in Scintilla, but it looks like the message not sent or something is went wrong. (Another Scintilla message like "move cursor left" works.)

The same message works with the NppExec plugin script: SCI_SENDMSG 2596 3 0 (source)

Steps to Reproduce the Issue

Edit shortcuts.xml add this code snippet inside the <Macros>...</Macros> tag:

<Macro name="Enable virtual space" Ctrl="no" Alt="no" Shift="no" Key="0">
    <Action type="0" message="2596" wParam="3" lParam="0" sParam="" />
</Macro>
<Macro name="Move cursor left" Ctrl="no" Alt="no" Shift="no" Key="0">
    <Action type="0" message="2308" wParam="0" lParam="0" sParam="" />
</Macro>

Expected Behavior

After run the "Enable virtual space" macro I can put the caret beyond line end with mouse.

Actual Behavior

Nothing.
