Issues with function keys

[garz]

This is probably the most basic question in the world and any help is really appreciated. I have a DM800 HD running Nemesis 2.6. My issue is I can't find the extras I have downloaded. I note from early versions it suggests multiple remote key presses but this does not seem to work for me. I presume I am missing something really basic.

Function keys:
• BLUE - Panel Nemesis
• BLUE> 1s Extensions
• 2x BLUE - Addons
• Yellow - Timeshift
• YELLOW> 1s Plugin
• GREEN-EPG Control Center
• GREEN> 1s subservices
• RED - Record Menu

Thanks in advance
