previous next page (not topic) with keyboard shortcut

[hitsme]

can some guide me the way to add to a topic "previous" "next" page (not topic) with keyboard shortcut?
is it a minor thing to do?

i see that wap has it for wap browsers

i understand that it would be as easy as adding something similar to this

Code Select Expand

<a href="$previous" accesskey="b">previous</a>
<a href="$next" accesskey="n"> next</a>

if i would only know where the pagination is constructed

wap declares it in Wireless.template.php

Code Select Expand

<p class="windowbg">[#] <a href="' . $context['links']['next'] . ';wap2' . $context['wireless_moderate'] . '" accesskey="#">' . $txt['wireless_navigation_next'] . '</a></p>' : '', !empty($context['links']['prev']) ? '
<p class="windowbg">[*] <a href="' . $context['links']['prev'] . ';wap2' . $context['wireless_moderate'] . '" accesskey="*">' . $txt['wireless_navigation_prev'] . '</a></p>' : '', $context['can_reply'] ? '

I believe it's somewhere here in subs.php
that you could add this

Code Select Expand

<a href="$previous" accesskey="b">previous</a>
<a href="$next" accesskey="n"> next</a>

I don't necessarily need a previous next  button

For example in this case

Pages: 1 2 3 4 [5] 6 7 8 9 10 11 ... 92   Go Down

When someone click alt `P` it goes to page number 4, and alt `N` takes you to page number 6
