Programming keyboard

Is there a way to program Page Up and Page Down, for example, to a Ctl+ please?

This would enable me to keep right hand on the mouse and complete these operations with the left hand.

This is on a MS Wireless Natural Multimedia Keyboard.

Thanks in advance for any help.

Many thanks, Andrew.

Andrew. Have tried several times to download the progam without success, then cleared the Chrome browser cache and tried again. Just keep getting the message, 'Failed - Network Error'. Any suggestion/s please?

OK. Program installed now. That just brings up a Notepad page with a couple of examples, which I understand. Those are the keystrokes but there is nothing about which keyboard key these might be aligned to. Secondly, down the bottom it says,

Please read the QUICK-START TUTORIAL near the top of the help file.
; It explains how to perform common automation tasks such as sending
; keystrokes and mouse clicks. It also explains more about hotkeys.

But the only page I can get is the Notepad page, and the Help on that obviously doesn't relate to Hotkeys.
I am not a techi but though the process might have been fairly straight forward. But am I doing something stupid or, is there something blatantly obvious which I am missing?

Help! again, if you wouldn't mind please, Andrew.

OK, THANKS, Andrew. Will try Firefox and/or IE. That works in Firefox. See other reply please.
