Some actions are simply adding extra keys to existing keyboard controls such that they can be remapped to suit a remote.
Other actions (such as Exit) are adding keyboard/remote controls to functions not normally available.

Existing actions can have their keys changed in the extension options.

Default Keys:
keyboard press: "P", "Shift+P", "Ctrl+P" or "Pause/Break" -> turns into: keypress Space, ie play/pause

keyboard press: "Escape" -> turns into: Close tab (and go back to xbmc)

keyboard press: "]" -> turns into: keypress arrow up = Volume up

keyboard press: "[" -> turns into: keypress arrow down = Volume down

keyboard press: "Enter" or "R" -> turns into: Reload web page (sometimes streaming fails and needs a reload)

keyboard press: "Space" -> at end of episode during countdown to next show, this will jump straight to next show. Also, if auto start new episode sometimes there's a popup asking if you want to continue watching, this will trigger continue button
