You cannot remove the next button on a <surveypage>, you can however place it off-screen via the page's /nextbuttonposition attribute.

<surveypage somepage>
/ caption = "The button is off-screen. Press TAB and then ENTER to move on."
/ nextbuttonposition = (110%, 110%)
</surveypage>

My question is related: is there a way of removing/disabling next button on Surveypages? We don't want the participants to close Inquisit when they are on the last page of their experiment. Another solution I came up with is to replace it with a trial and text elements with very long delay, but I am not sure if it works properly. Any other ideas?

No. If you want to prevent back-navigation, don't use instruction pages (<page> & <htmlpage> elements). Instead display your instructions using standard, <text>, <trial>, etc. elements.

To return to this question, is there a way to get rid of the before button on the instruction page?

You can change in using the command

> The question was "how to get rid of this button".That's not how I understood the original question. The fact is that instruction pages allow for navigating back and forth between them -- that's why there ought to be *two* navigation buttons. The behavior of those buttons is configured via the attributes I mentioned.

The question was "how to get rid of this button". From what I get, it's not possible with the parameters you described.

The attributes you need to define to alter instruction page navigation behavior are <instruct>

/ lastlabel = "label"
/ nextkey = ("character") or (scancode) or (signal)
/ nextlabel = "label"
/ prevkey = ("character") or (scancode) or (signal)
/ prevlabel = "label"
