Actually it speaks about "the line marker [...] and the search marker",
no indicator here.

I'd say that the doc is not clear on what this does, but it works
properly.  These values are used for the markers 0 (GCS_MARKER_LINE,
line marker used e.g. when triggering "got tag definition") and 1
(GCS_MARKER_MARK, user marker).

These markers are generally displayed as a symbol in the marker margin
(either an arrow or a plus sign), but are drawn as a line background if
the marker margin isn't visible (View->Editor->Display Marker Margin).
The translucency value is used only when drawing that background (see
Scintilla docs:
http://www.scintilla.org/ScintillaDoc.html#SCI_MARKERSETALPHA).

The search marker (GCS_MARKER_SEARCH, which actually is an indicator)
however has an hard-coded alpha value of 60 (highlighting.c:680.


Maybe changing the docs from:

> Translucency for the line marker (first argument) and the search
> marker (second argument). Values between 0 and 256 are accepted.

to:

> Translucency for the line marker (first argument) and the user
> marker (second argument) when drawn as a line background.  Values
> between 0 and 256 are accepted.

may help.


Hope it helps.
