Screenshot please ? If it's for "header" : {SAVE_LINKS} and {CLEARALL_LINKS} work without need of SAVE and CLEARALL.
Manual need update

Screenshot: look at any survey, with or without {SAVE} {CLEARALL} in navigator.pstpl... There is just no visible difference.

In what template file can I find {SAVE_LINKS} and {CLEARALL_LINKS}?

The {CLEARALL_LINKS} placeholder simply inserts an anchor element that is used to click the #clearall element inserted via {CLEARALL}.

The point is that if there is no {CLEARALL}, then {CLEARALL_LINKS} shouldn't be rendered - there is nothing to click.

@tammo - those placeholders are in startpage.pstpl.

@tpartner {CLEARALL_LINKS} work out of the box in 3.0 : no need {CLEARALL}.

You can use {CLEARALL_LINKS} without {CLEARALL} : this is the fact.
Even in the old 25X with removing CLEARALL : it work : http://testing.sondages.pro/answershtml/index.php/899541

See https://github.com/LimeSurvey/LimeSurvey/commit/f2b923e1b30f4281e65e103ae4d1a5ca4af06518

The (action_LINK} need js, the {action} don't need js if is inside form.

It's a documentation issue, not a code issue.

@DenisChenu, it may be fixed in 3.x but it is not fixed it 2.56.1.

I just tested with a new pull, and if the {CLEARALL} placeholder is removed, clicking on the inserted {CLEARALL_LINKS} element does nothing.

OK, then not me . I totally rework all HTML, and move 'template' function to 'core' function for this reason.
This is managed in template.js , not elsewhere : we can not fix it in user template.

template engine is rewritten in develop branch.

Right. I guess some more errors will be resolved this way
