How can I send the key "page up" when I press right button of the mouse and move up?

Don't know if it's possible to send a Key directly (don't think so), or if the page-up-command already exists somewhere by default in newer KM (well possible).
Anyway, try this little macro and report if it works?

Write this line:
ScrollUp1{injectJS("window.scrollByPages(-1);");}

into a kmm-file of your choice. Or create a new one with notepad and save as (whatever...).kmm into the macros folder. Make sure the file has no hidden txt-ending. Restart the browser.

Now open page "about:config", confirm the warning, and set this pref:
kmeleon.plugins.gestures.up = macros(ScrollUp1)

If it works okay, you may want to get this macro available into the gestures choice menu for easier handling in the future.
If things still are as in KM1.6 (?), there's somewhere a file named gestures.xml. Add this inside:

command="macros(ScrollUp1)"/>
<action caption="&macrosScrollUp1;"

It's working.
Thanks.

Okay, thanks for confirmation.

PS: had a typo above, in the gestures.xml (was "scrollup1" not "ScrollUp1", oops)
command="macros(ScrollUp1)"/>
