You can do this with the Search. If you hover over a search result you will see at the bottom of the window, the address of the topic to which it is linked.
I have tried changing the settings for generating and changing the skin. I have tried it is Firefox and Internet Explorer. It is happenning in projects converted from RoboHelp 7and new projects in RoboHelp 8. I have tried having other people create the projects and it still happens.
1. You can change what's displayed in the status bar by using windows.status, such as: onmouseover="window.status='text'; return true" within the the hyperlink tag. To do this, you have to add this by editing whibody.js to let Robo add the onmouseover to the hyperlink. (probably line 90 and 104)
2. I see now easy solution to let users right click to open the entry in a new page. Robohelp uses a script (function PopupMenu_Invoke() ) and I see no simple way to avoid this, unless you want to completely rewrite the script.
The script checks if there are multiple targets (topics) and displays a popup if there are. You can (probably) change the script so all pages opened from the index open in a new window, by changing the function PopupMenu_Invoke(), but I think that the target that is defined there, works for opening topics as well as opening the popup.
Ps. Sorry for the maybe's and probably's, but I don't have the time to sort this out now
